commit: Always enable efficient recursive tree listings
In commit 08507b22 (commit: Convert GetTreeEntries to use git-ls-tree(1), 2021-11-08), we have introduced an alternative implementation for the GetTreeEntries RPC for recursive listings, which uses git-ls-tree(1) instead of manually parsing and walking down the trees. This implementation has been rolled out on November 24th with the expected results: recursive tree listings on production are ~5-7x faster now.
Remove the feature flag and enable this new implementation by default.
Changelog: performance
Closes #3915 (closed)
