Make some tests better able to work with CR_ONE_TASK_PER_CORE

More testing required. This configuration is still disabled in
select_cons_tres.c

Add --ntasks-per-core option to execute line as needed

Without this change, test7.17 was failing

Cosmetic change
No change in logic

cosmetic change only

This can happen on node failure

Use stored pointer rather than pointer to pointer for
cleaner code. No change in logic.

Workaround involves specifying the index name when modifying an
existing index.
Bug 6303

The correct use of correct_query and query is clarified here.
Also adds saving the index name to parsing so correct_query
can be set to the correct "drop <index name>" for future query.
Bug 6303

This relocates a variable in order to move some common code into
one place rather than repeat it in several locations. No changes
to functionality, but simpler/less code.

The bitmap size should equal the GPU count not the MPS count
bug 6733

No change in logic other than additional logs

Note that using this feature in non-flat networks is not supported since the
sender address is set depending on the hostname resolution in each node.

Bug 6725

With schedulerparameters=defer and prolog scripts and/or spank plugins
that take some time, jobs weren't starting within 2 seconds that tests
2.18 and 2.19 expected, causing these tests to fail.

Bug 6670.

Bug 6127.

Doesn't set anything, and is not documented.

The option was removed in commit 8fceac46, but will likely be
restored in the future.

Bug 5303

IMO, the test as is currently designed is not representative of
an actual rpmbuild against a production released tarball, and thus
should not be relied on. Using --nodeps masks a lot of potential
errors with the spec file.

It has been disabled on Ubuntu systems for months, broken on master
for longer, and thus I am discarding it now.

Change to %pJ identifier while here and merge different partition
priorities into a single log message line.
