Code Issues Proposed changes

Removed deprecated *-floating-ip from procedures 

Switched out 'nova add-floating-ip' for 'nova floating-ip-associate'
and 'nova remove-floating-ip' for 'nova floating-ip-disassociate'.
Redid basic descriptions in End User Guide, and removed from Admin
User Guide.
Added floating-IP-bulk* procedures to the Admin User Guide (as the
only admin-specific procedures). Added references to EUG and CAG to
Admin User Guide.
