rockskip: Add ROCKSKIP_MIN_REPO_SIZE_MB to index repos over a certain size
Created by: chrismwendt
This adds ROCKSKIP_MIN_REPO_SIZE_MB
(defaults to 1000, or 1GB), which tells the symbols
service to index all repos over that size.
This makes it easier to set up Rockskip because you no longer have to explicitly list the repos in ROCKSKIP_REPOS
.

Ran locally.
