selftests: tc-testing: remove buildebpf plugin

As tdc only tests loading/deleting and anything more complicated is
better left to the ebpf test suite, provide a pre-compiled version of
'action.c' and don't bother compiling it in kselftests or on the fly
at all.

tc-testing: Clarify the use of tdc's -d option

The -d command line argument to tdc requires the name of a physical device
on the system where the tests will be run. If -d has not been used, tdc
will skip tests that require a physical device.

This patch is intended to better document what the -d option does and how
it is used.

tc-testing: Restore original behaviour for namespaces in tdc

This patch restores the original behaviour for tdc prior to the
introduction of the plugin system, where the network namespace
functionality was split from the main script.

It introduces the concept of required plugins for testcases,
and will automatically load any plugin that isn't already
enabled when said plugin is required by even one testcase.

Additionally, the -n option for the nsPlugin is deprecated
so the default action is to make use of the namespaces.
Instead, we introduce -N to not use them, but still create
the veth pair.

buildebpfPlugin's -B option is also deprecated.

If a test cases requires the features of a specific plugin
in order to pass, it should instead include a new key/value
pair describing plugin interactions:

"plugins": {
"requires": "buildebpfPlugin"
},

A test case can have more than one required plugin: a list
can be inserted as the value for 'requires'.

selftests: Introduce tc testsuite

Add the beginnings of a testsuite for tc functionality in the kernel.
These are a series of unit tests that use the tc executable and verify
the success of those commands by checking both the exit codes and the
output from tc's 'show' operation.

To run the tests:
# cd tools/testing/selftests/tc-testing
# sudo ./tdc.py

You can specify the tc executable to use with the -p argument on the command
line or editing the 'TC' variable in tdc_config.py. Refer to the README for
full details on how to run.

The initial complement of test cases are limited mostly to tc actions. Test
cases are most welcome; see the creating-testcases subdirectory for help
in creating them.
