Implement status handling for HTTPLocalRateLimitPolicy CRD

[alpeb]

This adds the status stanza to the HTTPLocalRateLimitPolicy CRD, and implements its handling in the policy status controller.

For the controller to accept an HTTPLocalRateLimitPolicy CR it checks that:

• The targetRef is an existing Server
• If there are multiple HTTPLocalRateLimitPolicy CRs pointing to the same server, only accept the oldest one, or if created at the same time, the first in alphabetical order (that logic was moved from the inbound indexer to the status controller).
