Test 3.11, file inc3.11.9 only runs for some configurations, but
  assumes no leading zeros in node name suffix. When run with
  nodes named "nid[00001-00005]", the test converted the last
  number to it's numeric for and as making requests for
  "nid[00001-5]", which would fail.

Bug 4312

These tests were failing on a single node cluster

If running on a single node cluster with an epilog, the delay could
  cause this test to fail

In my testing with the cray job_submit plugin enabled it caused a
delay of the last step most likely because the gres wasn't ready quick
enough.

Bug 4431

This primarily happens regularly if

PrologFlags=contain

Where the output has a nodename (and usually a number in it)

Normal output is

salloc: Granted job allocation 31159
1

but if the allocation is delayed you get output like

salloc: Granted job allocation 31161
salloc: Waiting for resource configuration
salloc: Nodes snowflake4 are ready for job
1
salloc: Relinquishing job allocation 31161

Where the test would key on the number in snowflake4 and fail.

This change makes it so the number has to be the first thing seen.

Previous logic would continuously report command not responding,
  but not exit the wait loop. Only test15.# checked so far

No other options use underscores, so make these consistent with
the rest. Both old and new syntax is supported for now.

Change all 'verbose' option output to use dashes, and adjust
the testsuite to match.

Fix a few related documentation errors while here.
