external_storer: Add a log entry limit This is to ensure that we don't get uncapped log entries. Default is set to the first 20 logs being saved, and the next 980 being in a circualr queue (1000 entries in total). Tested: Added unit test to ensure that the queue works as intended. Also verified by injecting 1000 entries to ensure that the buffer indeed saves the first 20, and caps it 1000. ``` //LogEntry1: Created: ...Entries/66a97808-1e22-4c1e-b0f6-4b9eb7c714e7/index.json ... //LogEntry20: Created: ...Entries/9c07937a-9524-40f1-acef-19db73b46678/index.json //LogEntry21: Created: ...Entries/0bfb7ede-8020-4613-bfcf-5815ca176c79/index.json ... //LogEntry1001: Removed: ...Entries/0bfb7ede-8020-4613-bfcf-5815ca176c79 Created: ...Entries/31bdf3be-1e87-4e77-922d-9bbac09ac824/index.json ``` We can see that starting on the 1001st log, log entry 21 is deleted to make room.
