tc: python3, string formattings

This patch converts old type string formattings to new type string
formattings for adapting Linux Traffic Control (tc) unit testing suite
python3.

Linux Traffic Control (tc) unit testing suite's code quality improved is improved with this patch.
According to python documentation;
"The built-in string class provides the ability to do complex variable substitutions and
value formatting via the format() method described in PEP 3101. "
but the project was using old type formattings and new type string formattings together,
this patch's main purpose is converting all old types to new types.

Following files changed:
1. tools/testing/selftests/tc-testing/tdc.py
2. tools/testing/selftests/tc-testing/tdc_batch.py

Following PEP rules applied:
1. PEP8 - Code Styling
2. PEP3101 - Advanced Code Formatting

tools: tc-testing: Introduce plugin architecture

This should be a general test architecture, and yet allow specific
tests to be done. Introduce a plugin architecture.

An individual test has 4 stages, setup/execute/verify/teardown. Each
plugin gets a chance to run a function at each stage, plus one call
before all the tests are called ("pre" suite) and one after all the
tests are called ("post" suite). In addition, just before each
command is executed, the plugin gets a chance to modify the command
using the "adjust_command" hook. This makes the test suite quite
flexible.

Future patches will take some functionality out of the tdc.py script and
place it in plugins.

To use the plugins, place the implementation in the plugins directory
and run tdc.py. It will notice the plugins and use them.

tools: tc-testing: Command line parms

Separate the functionality of the command line parameters into "selection"
parameters, "action" parameters and other parameters.

"Selection" parameters are for choosing which tests on which to act.
"Action" parameters are for choosing what to do with the selected tests.
"Other" parameters are for global effect (like "help" or "verbose").

With this commit, we add the ability to name a directory as another
selection mechanism. We can accumulate a number of tests by directory,
file, category, or even by test id, instead of being constrained to
run all tests in one collection or just one test.
