dcache-bulk: add count and clear to archive admin commands

Motivation:

Convenience (not having to run query on the database
interpreter).

Modification:

Add commands to display the count instead of the
actual entry (as with requests and targets), and
also a command to clear/delete from the archive
table.

Result:

Friendlier admin interface.

Target: master
Request: 9.2

Requires-notes: yes
