Policy service fails to get legaltags' descriptions

The Policy service requests the descriptions of all legaltags assigned to records. The Legal service legaltags:batchRetrieve request is limited to 25 legaltags as input. The Search service can request policy evaluation for thousands of records. So, we can't use legaltag description info for writing policy rules.

Example: Lets say that there are 100 file records (opendes partition is used) that we are going to search for:

query : { "kind": "opendes:wks:dataset--File.Generic:1.0.0", "limit" :100 }

Set of records: test_data.txt

The Legal service log:
