**This is a follow-up to:elastic#211045 ## Summary This PR removes inefficiencies in prebuilt rule installation memory consumption. ### Before In the worst-case scenario: 1. All currently installed prebuilt rules were fully loaded into memory. 2. All latest rule versions from the rule packages were fully loaded into memory. 3. All base rule versions were pulled into memory, even though they were not used. 4. The algorithm then checked which rules could be installed and installed them all at once. ### After 1. Pull only aggregated information about installed rules (only `rule_id` and `versions`). 2. Pull the same lightweight aggregated info about the latest rules in the package. 3. Using the collected `rule_id`s, fetch rule assets and install them in small batches of up to 100 rules. (cherry picked from commit 6d9fc21)
