TODB: Incorrect or missing indexes

[shamrickus]

I'm submitting a ...

• bug report

Traffic Control components affected ...

• Traffic Ops

Current behavior:

Table topology has no last_updated index, but topology_cachegroup has two including the one for topology which is CREATE INDEX topology_last_updated_idx ON topology_cachegroup ....

Table phys_location has a typo in it's index. The name is listed as pys_location_last_updated_idx instead of phys_location_last_updated_idx

Expected behavior:

For topology, each table should have only one last_updated index.
For phys_location the index should be named correctly.

Minimal reproduction of the problem with instructions:

Run db/admin.go and inspect the schema.
