Subject: [PATCH net-next 1/1] tools: tc-testing: Can refer to $TESTID in test spec

At debug level 5 or above, the test script will pause just before
the post_suite functions are called.  This allows the tester to
inspect the system before it is torn down.

When processing the commands in the test cases, substitute
the test id for $TESTID.  This helps to make more flexible
tests.  For example, the testid can be given as a command
line argument.

As an example, if we wish to save the test output to a file
named for the test case, we can write in the test case:

"cmdUnderTest": "some test command | tee -a $TESTID.out"
