dcache-bulk: reset policy defaults

Motivation:

At the last WLCG DOMA BDT meeting it was suggested that
the normal usage pattern for STAGE requests would be
5000 requests per VO with each request containing 200
files.

We agreed we would reset the defaults on the bulk
policy properties to conform with this, since they
will be a major user of this API.

Modification:

Properties have been set to default to WLCG values.
Also decreased the number of targets in a shallow
request.

Also increased number of threads available for
target activities to 200.

Result:

Happier admin users.

Target: master
Request: 9.0
Request: 8.2
