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.

Make Podman pod operations that do not involve starting
containers (which needs to be done in a specific order) use the
same parallel operation code we use to make `podman stop` on
large numbers of containers fast. We were previously stopping
containers in a pod serially, which could take up to the timeout
(default 15 seconds) for each container - stopping 100 containers
that do not respond to SIGTERM would take 25 minutes.
To do this, refactor the parallel operation code a bit to remove
its dependency on libpod (damn circular import restrictions...)
and use parallel functions that just re-use the standard
container API operations - maximizes code reuse (previously each
pod handler had a separate implementation of the container
function it performed).
This is a bit of a palate cleanser after fighting CI for two
days - nice to be able to return to a land of sanity.

While reviewing #6784 I found myself having a lot of trouble
with this script: it was a complicated mix of case statement
and helper functions, requiring a reader to jump back and
forth between the two.
This PR defines a convention such that a given TEST_FLAVOR=foo
must have a corresponding _run_foo() handler function. The
goal is to have all TEST_FLAVOR-related code in one place,
or at least less scattered (integration and system tests
still rely on other helper functions).

In case os.Open[File], os.Mkdir[All], ioutil.ReadFile and the like
fails, the error message already contains the file name and the
operation that fails, so there is no need to wrap the error with
something like "open %s failed".
While at it
- replace a few places with os.Open, ioutil.ReadAll with
ioutil.ReadFile.
- replace errors.Wrapf with errors.Wrap for cases where there
are no %-style arguments.

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.

Previous to this commit, the entire suite of CI tasks run in a PR, run
again for every merge (a.k.a. branch push). This wastes time and
resources with substantively overlapping testing. The primary reason
to test on branch-push, is providing coverage for merge-semantics.
In other words, problems introduced due to the sequence of PR merging.
For this purpose, the vast majority of problems can be caught quickly by
a small subset of automated tests. If deeper debugging is necessary,
then opening a test-PR is a small price to ask for the enormous amount
of time/resource savings with more limited branch-push testing.

(that got accidentally dropped in the new Cirrus makeover).
Note that 'dotest' does not actually 'do tests', it's
only used for a small subset of tests.
Also, make logformatter work better in the new Cirrus setup.
Remove duplicate test/subtest, remove no-longer-used SPECIALMODE,
and make the Cirrus build/task display a little cleaner.

When validating code on a branch, determining a starting commit to check
from isn't as straightforward as it would seem. Default to using the
SHA from last time CI was green. If for some reason that isn't
available, use an obviously wrong value to cause an intentional
failure. Entirely skip this check on tag-push, since determining a
starting point is incredibly difficult to do automatically.

Reimplement CI-automation to remove accumulated technical-debt and
optimize workflow. The task-dependency graph designed goal was to
shorten it's depth and increase width (i.e. more parallelism). A
reduction in redundant building (and 3rd party module download) was
also realized by caching `$GOPATH` and `$GOCACHE` early on. This
cache is then reused in favor of a fresh clone of the repository
(when possible).
Note: The system tests typically execute MUCH faster than the
integration tests. However, contrary to a fail-fast/fail-early
principal, they are executed last. This was implemented due to
debug-ability related concerns/preferences of the primary
(golang-centric) project developers.
