Split HMS from SDP, such that HMS will live on as a separate product,
layered on the SDP.
Many of the files deleted here have already been copied to HMS. See
these HMS changes:
And this branch spec: SDP_Split_2019.2_HMS
In mkrep.sh, HMS-awareness is removed from mkrep.sh, a core SDP script, and
the '-f' (Full Setup) flag has been temporarily removed. This useful
functionality will be restored in an HMS script. This is a big change,
so shellcheck v0.6.0 was implemented to support it.
