Matthew Heon 43d010bd0f Fix parsing of Tmpfs field in compat create
Create is not formatted as `key=value` but rather `key:value`
(technically `path:option1,option2`). As such we can't use the
stringMapToArray function, and instead need to generate it
manually.

Fixes #9511

Ashley Cui 832a69b0be Implement Secrets
Implement podman secret create, inspect, ls, rm
Implement podman run/create --secret
Secrets are blobs of data that are sensitive.
Currently, the only secret driver supported is filedriver, which means creating a secret stores it in base64 unencrypted in a file.
After creating a secret, a user can use the --secret flag to expose the secret inside the container at /run/secrets/[secretname]
This secret will not be commited to an image on a podman commit

Matthew Heon 1ae410d19e Ensure the Volumes field in Compat Create is honored
Docker has, for unclear reasons, three separate fields in their
Create Container struct in which volumes can be placed. Right now
we support two of those - Binds and Mounts, which (roughly)
correspond to `-v` and `--mount` respectively. Unfortunately, we
did not support the third, `Volumes`, which is used for anonymous
named volumes created by `-v` (e.g. `-v /test`). It seems that
volumes listed here are *not* included in the remaining two from
my investigation, so it should be safe to just append them into
our handling of the `Binds` (`-v`) field.

Fixes #8649

Fix --arch and --os flags to work correctly
Currently podman implements --override-arch and --overide-os
But Podman has made these aliases for --arch and --os.  No
reason to have to specify --override, since it is clear what
the user intends.

Currently if the user specifies an --override-arch field but the
image was previously pulled for a different Arch, podman run uses
the different arch.  This PR also fixes this issue.

baude f430467453 Set log driver for compatability containers
when using the compatibility api to create containers, now reflect the
use of k8s-file as json-file so that clients, which are
unaware of k8s-file, can work.  specifically, if the container is using
k8s-file as the log driver, we change the log type in container
inspection to json-file.  These terms are used interchangably in other
locations in libpod/podman.

this fixes log messages in compose as well.

Add support for --platform
For docker compatibility we need to support --platform
flag.

podman create --platform
podman run --platform
podman pull --platform

Since we have --override-os and --override-arch already
this can be done just by modifying the client to split
the --platform call into os and arch and then pass those
options to the server side.

Joseph Gooch 0b1c1ef461 Implement --sdnotify cmdline option to control sd-notify behavior
--sdnotify container|conmon|ignore
With "conmon", we send the MAINPID, and clear the NOTIFY_SOCKET so the OCI
runtime doesn't pass it into the container. We also advertise "ready" when the
OCI runtime finishes to advertise the service as ready.

With "container", we send the MAINPID, and leave the NOTIFY_SOCKET so the OCI
runtime passes it into the container for initialization, and let the container advertise further metadata.
This is the default, which is closest to the behavior podman has done in the past.

The "ignore" option removes NOTIFY_SOCKET from the environment, so neither podman nor
any child processes will talk to systemd.

This removes the need for hardcoded CID and PID files in the command line, and
the PIDFile directive, as the pid is advertised directly through sd-notify.

With the advent of Podman 2.0.0 we crossed the magical barrier of go
modules.  While we were able to continue importing all packages inside
of the project, the project could not be vendored anymore from the
outside.

Move the go module to new major version and change all imports to
`github.com/containers/libpod/v2`.  The renaming of the imports
was done via `gomove` [1].

Add a `--replace` flag to the `container {create,run}` commands.
If another container with the same name already exists, it will

Adding this flag is motivated by #5485 to make running Podman in systemd
units (or any other scripts/automation) more robust.  In case of a
crash, a container may not be removed by a sytemd unit anymore.  The
`--replace` flag allows for supporting crashes.
