Workhorse polls /api/v4/geo/proxy endpoint when Geo is not enabled

In gitlab-org/charts/gitlab#3067 (comment 808750871), we noticed api_json.log filling up with requests from /api/v4/geo/proxy:

It looks like Workhorse is doing this as of !66491 (merged). It looks like there is a Goroutine that polls this endpoint every 10 seconds.

Questions:

1. Can we disable this if Geo isn't enabled?
2. Can we reduce the frequency of this check?
