If a job was submitted with a deadline and no time_limit or min_time,
but the system has a QOS MaxWall the job's time_limit would be set
to the QOS limit. Since there is no min_time specified, the QOS MaxWall
would be treated as a min and max time limit for the job and potentially
make the deadline impossible to satisfy. Now we set the min_time to
1 minute of there is a deadline, but no time_limit or min_time.

Also make sure the job is cancelled at the end of the test

Add TopologyParam option of "TopoOptional" to optimize network topology
    only for jobs requesting it.

Timeout stalled transfers and cleanup related data structures. Default
to wait five minutes since last update. Hook onto registration/ping message
type to trigger cleanup in a minimally invasive manner.

While here restructure certain functions to use list_* functions
rather than iterate on the structures.

Otherwise --mail-type=ALL will send an unexpected stage_out message back
to the user.

Siphash is a state of the art keyed hash function that is performance competitive with the usual non-cryptographic hash functions. It's used as the default hash function backing hash tables in e.g. Perl, Python, Rust, and so on. Here we initially use it for the gid cache hash table, and in the common xhash implementation.

step_ptr->job_ptr is already dereferenced several times by now, so
null check is unnecessary here.

If a job fails stage in, set its reason to BurstBufferOperation
with a string describing what happened. Previously the reason was
set to AdminHeld on stage-in failure.

tree width is different than the default.

Make default compression vary based on library availability.

A node's CPULoad was getting reset to NoVal on reconfiguration.
This change preserves the old value, which can fix a possible
race condition with respect to test4.13

Test previously failed with heterogeous nodes (i.e. different
