selftests: openvswitch: Be more verbose with selftest debugging.
The openvswitch selftest is difficult to debug for anyone that isn't
directly familiar with the openvswitch module and the specifics of the
test cases. Many times when something fails, the debug log will be
sparsely populated and it takes some time to understand where a failure
occured.
Increase the amount of details logged to the debug log by trapping all
'info' logs, and all 'ovs_sbx' commands.

selftests: openvswitch: Attempt to autoload module.
Previously, the openvswitch.sh test suites would not attempt to autoload
the openvswitch module. The idea was that a user who is manually running
tests might not even have the OVS module loaded or configured for their
own development. However, if the kernel module is configured, and the
module can be autoloaded then we should just attempt to load it and run
the tests. This is especially true in the CI environments, where the CI
tests should be able to rely on auto loading to get the test suite running.

selftests: net: Use the provided dpctl rather than the vswitchd for tests.
The current pmtu test infrastucture requires an installed copy of the
ovs-vswitchd userspace. This means that any automated or constrained
environments may not have the requisite tools to run the tests. However,
the pmtu tests don't require any special classifier processing. Indeed
they are only using the vswitchd in the most basic mode - as a NORMAL
switch.
However, the ovs-dpctl kernel utility can now program all the needed basic
flows to allow traffic to traverse the tunnels and provide support for at
least testing some basic pmtu scenarios. More complicated flow pipelines
can be added to the internal ovs test infrastructure, but that is work for
the future. For now, enable the most common cases - wide mega flows with
no other prerequisites.
Enhance the pmtu testing to try testing using the internal utility, first.
As a fallback, if the internal utility isn't running, then try with the
ovs-vswitchd userspace tools.
Additionally, make sure that when the pyroute2 package is not available
the ovs-dpctl utility will error out to properly signal an error has
occurred and skip using the internal utility.

This will be used when setting details about the tunnel to use as

Until recently, the ovs-dpctl utility was used with a limited actions set
and didn't need to have support for multiple similar actions. However,
when adding support for tunnels, it will be important to support multiple
set() actions in a single flow. When printing these actions, the existing
code will be unable to print all of the sets - it will only print the
first.
Refactor this code to be easier to read and support multiple actions of the
same type in an action list.

for this without polluting the datapath, so we introduce a mechanism
to clear all the flows from a datapath allowing us to test for
explicit drop actions, and then clear the flows to build the
original test case.
