Add org unit settings for default status of newly added copies

Add org unit settings for default status of newly added copies

These two new org unit settings enable sites to control the
default status of newly added copies. The defaults match
the behaviour of the "Add Volumes" ("In Process") and
"Fast Add" ("Available") interfaces as of Evergreen 1.6.1,
but sites can choose to have the copies go directly to
"Reshelving", "Available", or any other status defined in
config.copy_status.

The org unit settings are:

  * cat.default_copy_status_fast (for "Fast Add")
  * cat.default_copy_status_normal (for "Add Volumes")
