due to a lack of "locking" on cni operations, we could get ourselves in trouble when doing rapid creation or removal of networks. added a simple file lock to deal with the collision and because it is not considered a performent path, use of the file lock should be ok. if proven otherwise in the future, some generic shared memory lock should be implemented for libpod and also used here.
moved pkog/network to libpod/network because libpod is now being pulled into the package and it has therefore lost its generic nature. this will make it easier to absorb into libpod as we try to make the network closer to core operations.

We do not populate the hostname field with the IP Address

Docker supports log-opt max_size and so does conmon (ALthough poorly).
Adding support for this allows users to at least make sure their containers
logs do not become a DOS vector.

All containers within a Pod need to run with the same SELinux
label, unless overwritten by the user.
Also added a bunch of SELinux tests to make sure selinux labels
are correct on namespaces.

A podman could not read logs written to journald properly, due to a tail config bug.
Added a system test to check this - since e2e tests don't like journald

* --format "table {{.field..." will print fields out in a table with
headings. Table keyword is removed, spaces between fields are
converted to tabs
* Update parse.MatchesJSONFormat()'s regex to be more inclusive
* Add report.Headers(), obtain all the field names to be used as
column headers, a map of field name to column headers may be provided
to override the field names
* Update several commands to use new functions

The network test created config files with random filenames
but the network name was static. Since the tests can run in
parallel podman was not able to distinguish the networks.
We need to make sure that each test has its own config file
and network name. This helps to prevent unnecessary flakes.

The systemd test was inaccurately being skipped when a userns env. var.
flag was set. At best this is confusing to new developers, and at worse
it actively blocks an otherwise legitimate class of tests. Improve the
accuracy of skip-logic by adding/using a purpose built set of
functions.

If run&create image returns error: image contains manifest list, not a runnable image, find the local image that has digest matching the digest from the list and use the image from local storage for the command.

When looking up local images, take the unqualified-serach registries of
the registries.conf into account (on top of "localhost/").
Also extend the integration tests to prevent future regressions.

We need to handle removal of non existing network.
This allows the `removeCNINetwork` function
always to be called. This is needed by tests which are trying
to remove the network manually in order to prevent flakes.

Test passes on Fedora because the registry server is one of the
defaults. However it is not typically configured on Ubuntu hosts, and
therefor this test can fail. While specifying the FQIN in the
dockerfile text is not an ideal solution, it cannot negatively
affect other tests which utilize `podmanTest.BuildImage`.

Fix the remote client to untag all tags of the specified image.
Instead of querying the image on the client side, support the
case where both, repo and tag, are empty and remove all tags.
Reuse the ABI implementation where possible. In retrospective,
the libpod untag endpoint should support a slice of strings to
batch remove tags rather than reaching out for each tag individually.
Enable the skipped test.

In podman containers rm and podman images rm, the commands
exit with error code 1 if the object does not exists.
This PR implements similar functionality to volumes, networks, and Pods.
Similarly if volumes or Networks are in use by other containers, and return
exit code 2.
