Update acisops/acis_thermal_check to 3.7.1

[javierggt]

This is a small update to Release 3.7.0 which writes the .hist files in a different directory. 3.7.0 was neither approved nor installed so approval of this release is also an approval of 3.7.0

Change Description

Recently, SCS-106 was updated to leave 3 FEPs on rather than no FEPs on.
SCS-106 is run as part of the SCS-107 sequence.

Therefore thermal model history assembly requires that this change be reflected
in any shutdown: both science-only shutdowns as well as Full Stops. Also, the
ACIS Team recently added new power commands which have to be handled by Backstop History.

These were the drivers for the release of this version of Backstop History.
Several changes had been underway for some time and are incorporated in this release.

The previous version of Backstop History and acis_thermal_check (ATC) placed a major loop
inside the ACISStateBuilder class of state_builder.py wherein ATC was controlling the assembly
of a backstop history. Presently, ATC detects when to end the backchaining and also assesses
the types of loads (Normal, TOO, SCS-107, Full Stop) for each load in the backchain.
These functions belong inside Backstop History so that All ATC does is request an assembled
history given the pertinent information needed at the start of the assembly. This was
removed from ATC and moved into Backstop History. In addition, the need for a function
to convert backstop commands from a list of dict to a CommandTable is removed.

In the present production version of Backstop History, no record was kept of the assembled history.
In this new version, after a command history has been fully assembled, including any
necessary command sequences (e.g. LTCTI's, Maneuvers, SCS-107 etc.) a CR*.backstop.hist
file is written out to the directory specified by the model argument --outdir: the root of the file name
being the same as the review load CR*.backstop file, with ".hist" appended. This .hist file
is written out in CR*.backstop format and can be run through a model. This provides
both special case testing (using a test NLET file) as well as a means to check the resultant
output of Backstop History.

CTI command and maneuver templates were removed from the code and transformed into a data file.
This file can be updated as new power commands are created without touching the executable code.
Also one file that contained a variety of command definitions (e.g. AA0000000) is eliminated.
This, in turn eliminated classes and simplified the code.

Methods that were never used in Backstop History were removed.

A local logger was build for Backstop History which will identify the source of the
logger message. The level of verbosity is captured by ATC and passed to the ACIS state
builder.

Also includes changes John made which make the role of the run_start argument much more clear.

Comments were added or modified for clarification.

Files Changed:

Original SCS-106 changes merged but not yet put into production:
acisops/backstop_history#20
acisops/backstop_history#21

Additional PR's which write the .hist files to the model --outdir directory:

acisops/acis_thermal_check#41
acisops/acis_thermal_check#42

Both PR's 21 and 42 must be merged at the same time.

Testing:

These regression tests were run on the 1DPAMZT and ACISFP_CHECK models.

Deployment Plan

Installation of Backstop History and acis_thermal_check will occur after the
start of execution of this week's Review Load.

Includes the following merges:

• PR #42: Write .hist files to --outdir directory
