Adds some header detection to help prevent DDOS attempts on the
repository archive endpoint. Introduced as a concern so it can
be utilised elsewhere if needed.

Now uses built-in Rails header parser and doesn't block
legimate Sec-Fetch-Mode headers.

Adds support for hotlinking interception on the API as well, refactors
most of the system out into a new class to cover both Rails and Grape.

Cache ES enabled namespaces and projects

See merge request gitlab-org/gitlab!27348

SELECT query involving `elasticsearch_indexed_projects` table
consumes a lot of resources. The query itself is not slow
(13.224 ms/call), but it happens almost 100 times per second.

This change implements caching of `elasticsearch_indexed_projects` and
`elasticsearch_indexed_namespaces`.
