Fixes #5088 #2524 - adding taxonomy related parameters to apidocs

- new param group `taxonomy` for taxable resources
- new param group `taxonomy_scope` for index actions of taxable resources
- pagination and search param moved to a group `search_and_pagination` to reduce duplicities
@mbacovsky, are you sure `Location.find_by_id(nil)` raises an exception without the `!`. My guess is that you had `Location.find_by_id!(nil)`
