Added preliminary files in support of automation of the HMS
Tight Ship installation.
The key file here hs hms_ts_setup.sh, which is currently a 'doc only'
script that documents what it is intended to do, although it doesn't
currently do anything that affects data. The '-h' and '-man' flags
work to convey their intent.
This also contains various spec files to be used in the actual
implementation.
Bypassing pre-commit review since this is only adding new 'doc only'
code, not active software.
