Rebuild UMAPI Cache Tables After Version Change

[ddybvig-perf]

Is your feature request related to a problem? Please describe.
When the version is incremented for the UMAPI Cache, we should drop the existing cache tables and then rebuild them to make sure that they conform to any schema changes that accompanied the version change.

Describe the solution you'd like
When the version is incremented, a new method should be called to drop and then rebuild the UMAPI cache tables. We should also re-initialize the cache meta and set should_refresh to true.
