Cache repository locations in LocalDiskRepositoryManager

Obtaining the actual location of a repository using base-path
and project name can be slow as it involves some guessing to
locate the repository. Cache the locations once they are
obtained to avoid repeated work, thereby improving performance
when opening repositories.

For example, on a site with 20k repositories on NFS, ls-projects
with this change takes ~60s and ~90s without. Also, a query which
wraps a large (~2k) list of manifest[1] operators will take ~300ms
with this change and ~2s without it.
