MAINT: get_info s3df compatibility

[ZLLentz]

Description

• rename get_info to get_info.py and wrap in a get_info bash script
• use the bash script to select a python environment based on which is available
• do not activate the full environment for speed, this is sufficient for get_info

Motivation and Context

• User group wants to use these utilities in s3df
• In general, this is a helpful thing to have
• https://jira.slac.stanford.edu/browse/ECS-5069
• It seems wrong to rebuild the entire controls conda env on s3df, a system without controls

How Has This Been Tested?

I set my PATH to my clone of engineering tools and removed the previous tagged engineering tools from my PATH. Then I verified functionality and failure modes on both systems:

Basic functionality (using get_lastRun): It's the same results in each system which is a good sign.

zlentz@psbuild-rhel7-02:~/.../engineering_tools/scripts(mnt_get_info_s3df -)$ ./get_lastRun -H xpp
5
zlentz@psbuild-rhel7-02:~/.../engineering_tools/scripts(mnt_get_info_s3df -)$ ./get_lastRun -H tmo
131
zlentz@psbuild-rhel7-02:~/.../engineering_tools/scripts(mnt_get_info_s3df -)$ ./get_lastRun -H cxi
18

[zlentz@sdfiana008 scripts]$ ./get_lastRun -H xpp
5
[zlentz@sdfiana008 scripts]$ ./get_lastRun -H tmo
131
[zlentz@sdfiana008 scripts]$ ./get_lastRun -H cxi
18

Basic functionality using the script directly seems to work too:

zlentz@psbuild-rhel7-02:~/.../engineering_tools/scripts(mnt_get_info_s3df -)$ ./get_info --exp --hutch XPP
xppl1026722

[zlentz@sdfiana008 scripts]$ ./get_info --exp --hutch XPP
xppl1026722

Error state if the python interpreters are both not found (by modifying the script to look for the wrong ones): It tells you why it isn't running and what it tried to use.

zlentz@psbuild-rhel7-02:~/.../engineering_tools/scripts(master +)$ ./get_lastRun -H xpp

Error codes from get_info.py are properly passed to get_info:

zlentz@psbuild-rhel7-02:~/.../engineering_tools/scripts(mnt_get_info_s3df -)$ ./get_info asefasfe
usage: get_info.py [-h] [--run] [--exp] [--live] [--ended] [--hutch HUTCH]

zlentz@psbuild-rhel7-02:~/.../engineering_tools/scripts(mnt_get_info_s3df -)$ echo $?

Where Has This Been Documented?

Only here, in the release notes later, and in the jira ticket

exactly what we wanted. i will test it with the users.
