Joachim Wiberg 44d37808f1 test/case: use 9pm 'name:' for all test names
To reduce the duplication of effort between 9pm and the Infamy framework
this change consolidates the move from local 'infamy: title:' extension
to 9pm 'name:'.

For the parameterized tunnel tests we leverage the 9pm dynamic test-spec
variable, which looks for a correspodning <case>.adoc instead of static
Readme.adoc, when generating the test report.

Each test documentation should cover all aspects of the test, much like
the usage text of a UNIX program.  To this end, the tunnel test docs are
now more spelled out, including all invariants.

Some refactoring of these tests were also necessary, e.g., replacing any
reserved Python keywords like 'type', and other PEP-8 fixes.
