Rename Beam Destinations to Ops Destinations

[slominskir]

There are many activities besides sending beam that occur in the facilities including:

• RF Operations
• PSS Certifications
• Others?

Instead of creating separate lists, we could use a single list and rename it. Lots of places to rename!

Dev Note: Ideally code variables are internally renamed too to avoid future confusion (tech debt), but then this change effort explodes. Plus, Oracle database schema changes too!
