artifact mount: add new name option to specify filename
An artifact without the title annoation just gets the digest as name
which is less than ideal. While it is a decent default to avoid
conflicts users would like to configure the name.

With the name=abc option we will call the file abc in case of a signle
artifact and otherwise we use abc-x where x is the layer index starting
at 0 to avoid conflicts.

Clarified the consequences of --network=host
The prior version talked about potential access to DBus, but this is a
bogus warning: default OS setups do not bind DBus to localhost or to an
abstract Unix socket.  It is possible that the original author was
thinking of CVE-2020–15257, which affected containerd's abstract Unix
socket; they fixed it by switching to a named socket, just as DBus
always (?) has done.

Matthew Heon 775a85004f Add "dest" as an alias for "destination" in `--mount`
Given I wrote this and I still mess it up on a regular basis, I
cannot be alone in forgetting whether "dst" or "dest" is the
correct short option for "destination". Let's just make both
valid, I don't see a reason not to.

Fix overwriting the Healthcheck configuration from the image
If the --health-cmd flag is not specified, other flags such as --health-interval, --health-timeout, --health-retries, and --health-start-period are ignored if the image contains a Healthcheck. This makes it impossible to modify these Healthcheck configuration when a container is created.

Jan Kaluza 701aade262 Add --env and --unsetenv to podman update.
The --env is used to add new environment variable to container or
override the existing one. The --unsetenv is used to remove
the environment variable.

It is done by sharing "env" and "unsetenv" flags between both
"update" and "create" commands and later handling these flags
in the "update" command handler.

The list of environment variables to add/remove is stored
in newly added variables in the ContainerUpdateOptions.

The Container.Update API call is refactored to take
the ContainerUpdateOptions as an input to limit the number of its
arguments.

The Env and UnsetEnv lists are later handled using the envLib
package and the Container is updated.

The remote API is also extended to handle Env and EnvUnset.

add new artifact mount type
Add a new option to allow for mounting artifacts in the container, the
syntax is added to the existing --mount option:
type=artifact,src=$artifactName,dest=/path[,digest=x][,title=x]

This works very similar to image mounts. The name is passed down into
the container config and then on each start we lookup the artifact and
the figure out which blobs to mount. There is no protaction against a
user removing the artifact while still being used in a container. When
the container is running the bind mounted files will stay there (as the
kernel keeps the mounts active even if the bind source was deleted).
On the next start it will fail to start as if it does not find the
artifact. The good thing is that this technically allows someone to
update the artifact with the new file by creating a new artifact with
the same name.

Brent Baude d7553fabc7 podman artifact
the podman artifact verb is used to manage OCI artifacts.  the following
verbs were added to `podman artifact`:

* add
* inspect
* ls
* pull
* push
* rm

Notable items with this PR:

* all artifact commands and their output are subject to change. i.e.
  consider all of this tech preview
* there is no way to add a file to an artifact that already exists in
  the store.  you would need to delete and recreate the artifact.
* all references to artifacts names should be fully qualified names in
  the form of repo/name:tag (i.e. quay.io/artifact/foobar:latest)
* i understand that we will likely want to be able to attribute things
  like arch, etc to artifact files.  this function is not available yet.

fixed issues early on.

Configure HealthCheck with `podman update`
New flags in a `podman update` can change the configuration of HealthCheck when the container is started, without having to restart or recreate the container.

This can help determine why a given container suddenly started failing HealthCheck without interfering with the services it provides. For example, reconfigure HealthCheck to keep logs longer than the usual last X results, store logs to other destinations, etc.

Michael Zimmermann 315e7412e8 add support for driver-specific options during container creation
This way has a huge disadvantage: The user will not see an error when he
uses a non-existent option. Another disadvantage is, that if we add more
options within podman, they might collide with the names chosen by
plugins. Such issues might be hard to debug.
The advantage is that the usage is very nice:
--network bridge:opt1=val1,opt2=val2.

Alternatively, we could put this behind `opt=`, which is harder to use,
but would solve all issues above:
--network bridge:opt=opt1=val1,opt=opt2=val2

Add --health-max-log-count, --health-max-log-size, --health-log-destination flags
These flags can affect the output of the HealtCheck log. Currently, when a container is configured with HealthCheck, the output from the HealthCheck command is only logged to the container status file, which is accessible via `podman inspect`.
It is also limited to the last five executions and the first 500 characters per execution.

This makes debugging past problems very difficult, since the only information available about the failure of the HealthCheck command is the generic `healthcheck service failed` record.

- The `--health-log-destination` flag sets the destination of the HealthCheck log.
  - `none`: (default behavior) `HealthCheckResults` are stored in overlay containers. (For example: `$runroot/healthcheck.log`)
  - `directory`: creates a log file named `<container-ID>-healthcheck.log` with JSON `HealthCheckResults` in the specified directory.
  - `events_logger`: The log will be written with logging mechanism set by events_loggeri. It also saves the log to a default directory, for performance on a system with a large number of logs.

- The `--health-max-log-count` flag sets the maximum number of attempts in the HealthCheck log file.
  - A value of `0` indicates an infinite number of attempts in the log file.
  - The default value is `5` attempts in the log file.
- The `--health-max-log-size` flag sets the maximum length of the log stored.
  - A value of `0` indicates an infinite log length.
  - The default value is `500` log characters.
