move to /home/dmtexec/calibration

This add systemd --user units for dmt-procmgt and gstlal-calibration.

The dmt-procmgt service is handled as a template, such that the
instance is DMT config dependent, e.g. 'dmt-procmgt@LLO_TestDQ' for
the l1dmt3 config.

The gstlal-calibration service uses an EnvironmentFile from
/home/dmtexec/config/gstlal-calibration-env to get the CONFIG_FILE and
FILTER_FILE directives.  An example env file is included.
