  1. python: add assumeFuture argument to flux.util.parse_datetime 

    Problem: The parse_datetime() utility function is statically configured
to assume future dates when a term like "Friday" is given. That is,
instead of giving the date for the previous Friday, the function will
return then next Friday instead. This behavior should be configurable.

Add an assumeFuture parameter to the function which defaults to True.
If set to False, then parse_datetime() will assume dates in the past
instead.

  2. python: add convert_values member to ConstraintParser class 

    Problem: Values are always returned as strings by the ConstraintParser
parser, but there are times when another type may be more
suitable. Additionally, there is currently no way to reduce a set
of values to a single element if this is required or beneficial in
the result.

Add a convert_values mapping to the ConstraintParser class. If an
operator is in this dictionary, then the values of a term are passed
to the provided callable, which should return a new list of values
as a result.

  3. python: add flux.job.info.strtostate and strtoresult 

    Problem: flux_job_strtostate(3) and flux_job_strtoresult(3) are not
exposed in the Python API.

Add strtostate() and strtoresult() to flux.job.info.

  4. python: add JobListConstraintParser 

    Problem: There is no user friendly way to create constraint objects
that can be used with the job-list service.

Add a JobListConstraintParser class which can be used to create
RFC 31 constraing objects suitable for sending to the job-list service.

  5. python: add flux.util.FilterActionConcatenate 

    Problem: The flux-jobs(1) -f, --filter option is being updated to
take a query string, but there is no "filter" based argparse action
to handle this case.

Add flux.util.FilterActionConcatenate which concatenates multiple
--filter strings together, separated by space.

  6. flux-jobs: support constraint query string with -f, --filter 

    Problem: There is no way to provide an arbitrary constraint to
flux-jobs(1).

Update the `-f, --filter` option of flux-jobs(1) to take a query string
that will be passed to the JobList constraint parameter instead of
the filter paramter.
