New catalogue table and respective cta-admin diskinstance and
cta-admin diskinstancespace commands

Activity Mount Rules associate a Mount Policy to an activity regex.

When recalling a file, the users can specify an activity (i.e. by using
filepath?activity=x). If specified, this activity will be used to select
a matching activity mount rule, if one exists. If more than one Activity
Mount Rule matches the activity, the one with highest retrieve priority
will be chosen.

Acitivity Mount Rules take precedence over Requester Mount Rules.

Changes VERSION to VERSION_CMD to avoid name clash with EOS VERSION
macro.

  vid, etc.)

- If --json output, print error message on stderr, print empty JSON
  array [] on stdout, and exit with code 2
