Feature #2781 PairStat wrapper (#2872)

* update release guide for METplus to create data location for next release on mohawk when creating rc1 release instead of after official release

* cleanup

* per #2781, start first implementation of PairStat wrapper

* appease SonarQube by increasing code coverage for component versions script

* add new wrapper to lookup dictionary

* per #2781 add wrapped MET config file

* use runtime freq logic to find input files

* start unit tests (broken)

* reorder assert to align expected and actual values with PyCharm notation

* update unit tests

* rename field info variable 'field' to 'pairs' to match Pair-Stat naming convention. Add command line arguments to pair_stat command

* reorder assert to align actual and expected in PyCharm

* refactor function to get start/end times to prevent error when using INIT/VALID_LIST and use time_generator to be more consistent and reduce duplicate code

* change many wrappers to be consistent with finding input files. Errors are now thrown when any input file is not found, checking other input types even when another input was not found. This increased errors reported in unit tests, so updated tests to reflect this.

* remove line that is not needed

* fix bug introduced with recent changes and run use cases that failed to test that the fix is correct

* fix multi-variate MODE run to pass all fields to the call instead of just the first one

* update SeriesAnalysis test to use logic that is actually used when running

* turn off use cases that now succeed and turn on use case to test fix to multi-variate mode

* turn off use case after confirming that it now runs successfully

* refactor logic to satisfy SonarQube to reduce cognitive complexity and remove unused imports

* remove functions that are not used

* handle -pairs flag like other command line args for input files. Add documentation to new functions

* updates to new wrapper, add documentation, basic use case stubs. create function for duplicate code to handle land_mask and topo_mask in PointStat and PairStat wrappers

* remove unused import

* remove config variable that is no longer used in MET

* remove match_month support from climo_mean/stdev

* remove obs_valid_beg/end from command line args because it is not supported by pair_stat

* remove test config files that are not being used

* configure basic use case to run command that is being used to test/develop the app

* error if invalid tool name is provided

* add missing tests

* remove support for config variables that did not make it into the final implementation of the MET pair_stat tool

* fix formatting on a few config values

* correct input file info

* turn on use case to test

* fix command line argument for output directory that changed since the last test

* refactor and clean up to reduce SonarQube issues

* update use case to prevent redundant runs of SeriesAnalysis(run_two) by only setting custom loop list for the first instance of SeriesAnalysis

* Fix bug that prevents correct field information from being set when multiple fields are read from the same file. Removed unused function

* per feedback in PR #2872, remove support for setting output_prefix

* add PairStat to list of wrappers that use the MODEL config variable

* per feedback in PR #2872, modify wrapper behavior to change output path from a directory to a filename base that will be used to write output files with various extensions, e.g. _mpr.txt or .stat

* remove output_prefix from tables
