codeintel: Rate limit auto-indexing requests to repo-updater/gitserver
Created by: efritz
Limit the (significant) requests we make to gitserver and repo-updater for auto-indexing tasks. We can control the rate of requests from a service with the following envvars:
PRECISE_CODE_INTEL_AUTO_INDEX_MAXIMUM_REPOSITORIES_INSPECTED_PER_SECOND
PRECISE_CODE_INTEL_AUTO_INDEX_MAXIMUM_REPOSITORIES_UPDATED_PER_SECOND
PRECISE_CODE_INTEL_AUTO_INDEX_MAXIMUM_INDEX_JOBS_PER_INFERRED_CONFIGURATION
