support advanced network configuration via cli
Rework the --network parse logic to support multiple networks with
specific network configuration settings.
--network can now be set multiple times. For bridge network mode the
following options have been added:
  - **alias=name**: Add network-scoped alias for the container.
  - **ip=IPv4**: Specify a static ipv4 address for this container.
  - **ip=IPv6**: Specify a static ipv6 address for this container.
  - **mac=MAC**: Specify a static mac address address for this container.
  - **interface_name**: Specify a name for the created network interface inside the container.

So now you can set --network bridge:ip=10.88.0.10,mac=44:33:22:11:00:99
for the default bridge network as well as for network names.
This is better than using --ip because we can set the ip per network
without any confusion which network the ip address should be assigned
to.
The --ip, --mac-address and --network-alias options are still supported
but --ip or --mac-address can only be set when only one network is set.
This limitation already existed previously.

The ability to specify a custom network interface name is new

network connect allow ip, ipv6 and mac address
Network connect now supports setting a static ipv4, ipv6 and mac address
for the container network. The options are added to the cli and api.

network reload without ports should not reload ports
When run as rootless the podman network reload command tries to reload
the rootlessport ports because the childIP could have changed.
However if the containers has no ports we should skip this instead of
printing a warning.

always add short container id as net alias
This matches what docker does. Also make sure the net aliases are also
shown when the container is stopped.

docker-compose uses this special alias entry to check if it is already
correctly connected to the network. [1]
Because we do not support static ips on network connect at the moment
calling disconnect && connect will loose the static ip.

Fix network aliases with network id
When a network id is used to create a container we translate it to use the
name internally for the db. The network aliases are also stored with the
network name as key so we have to also translate them for the db.

Also removed some outdated skips from the e2e tests.

Ed Santiago 547fff2703 e2e tests: use Should(Exit()) and ExitWithError()
e2e test failures are rife with messages like:

   Expected 1 to equal 0

These make me cry. They're anti-helpful, requiring the reader
to dive into the source code to figure out what those numbers
mean.

Solution: Go tests have a '.Should(Exit(NNN))' mechanism. I
don't know if it spits out a better diagnostic (I have no way
to run e2e tests on my laptop), but I have to fantasize that
it will, and given the state of our flakes I assume that at
least one test will fail and give me the opportunity to see
what the error message looks like.

THIS IS NOT REVIEWABLE CODE. There is no way for a human
to review it. Don't bother. Maybe look at a few random
ones for sanity. If you want to really review, here is
a reproducer of what I did:

   cd test/e2e
   ! positive assertions. The second is the same as the first,
   ! with the addition of (unnecessary) parentheses because
   ! some invocations were written that way. The third is BeZero().
   perl -pi -e 's/Expect\((\S+)\.ExitCode\(\)\)\.To\(Equal\((\d+)\)\)/Expect($1).Should(Exit($2))/' *_test.go
   perl -pi -e 's/Expect\((\S+)\.ExitCode\(\)\)\.To\(\(Equal\((\d+)\)\)\)/Expect($1).Should(Exit($2))/' *_test.go
   perl -pi -e 's/Expect\((\S+)\.ExitCode\(\)\)\.To\(BeZero\(\)\)/Expect($1).Should(Exit(0))/' *_test.go

   ! Same as above, but handles three non-numeric exit codes
   ! in run_exit_test.go
   perl -pi -e 's/Expect\((\S+)\.ExitCode\(\)\)\.To\(Equal\((\S+)\)\)/Expect($1).Should(Exit($2))/' *_test.go

   ! negative assertions. Difference is the spelling of 'To(Not)',
   ! 'ToNot', and 'NotTo'. I assume those are all the same.
   perl -pi -e 's/Expect\((\S+)\.ExitCode\(\)\)\.To\(Not\(Equal\((0)\)\)\)/Expect($1).To(ExitWithError())/' *_test.go
   perl -pi -e 's/Expect\((\S+)\.ExitCode\(\)\)\.ToNot\(Equal\((0)\)\)/Expect($1).To(ExitWithError())/' *_test.go
   perl -pi -e 's/Expect\((\S+)\.ExitCode\(\)\)\.NotTo\(Equal\((0)\)\)/Expect($1).To(ExitWithError())/' *_test.go
   ! negative, old use of BeZero()
   perl -pi -e 's/Expect\((\S+)\.ExitCode\(\)\)\.ToNot\(BeZero\(\)\)/Expect($1).Should(ExitWithError())/' *_test.go

Run those on a clean copy of main branch (at the same branch
point as my PR, of course), then diff against a checked-out
copy of my PR. There should be no differences. Then all you
have to review is that my replacements above are sane.

UPDATE: nope, that's not enough, you also need to add gomega/gexec
to the files that don't have it:

   perl -pi -e '$_ .= "$1/gexec\"\n" if m!^(.*/onsi/gomega)"!' $(grep -L gomega/gexec $(git log -1 --stat | awk '$1 ~ /test\/e2e\// { print $1}'))

UPDATE 2: hand-edit run_volume_test.go

UPDATE 3: sigh, add WaitWithDefaultTimeout() to a couple of places

UPDATE 4: skip a test due to bug #10935 (race condition)

Paul Holzinger 4462113c5e podman network reload add rootless support
Allow podman network reload to be run as rootless user. While it is
unlikely that the iptable rules are flushed inside the rootless cni
namespace, it could still happen. Also fix podman network reload --all
to ignore errors when a container does not have the bridge network mode,
e.g. slirp4netns.

Paul Holzinger aa0a57f095 Fix cni teardown errors
Make sure to pass the cni interface descriptions to cni teardowns.
Otherwise cni cannot find the correct cache files because the
interface name might not match the networks. This can only happen
when network disconnect was used.

Paul Holzinger 9d818be732 Fix podman network IDs handling
The libpod network logic knows about networks IDs but OCICNI
does not. We cannot pass the network ID to OCICNI. Instead we
need to make sure we only use network names internally. This
is also important for libpod since we also only store the
network names in the state. If we would add a ID there the
same networks could accidentally be added twice.

Paul Holzinger 5c6ab3075e Fix podman network disconnect wrong NetworkStatus number
The allocated `tmpNetworkStatus` must be allocated with the length 0.
Otherwise append would add new elements to the end of the slice and
not at the beginning of the allocated memory.

This caused inspect to fail since the number of networks did not
matched the number of network statuses.
