Adam Simpkins 59ff8f90b5 remove the config parameter from LocalStore
Summary:
The `LocalStore` constructor was updated to accept a `ReloadableConfig`
argument in D12949577, but this was never used anywhere.  Remove it for now to
help simplify the code.  If we do want to add it back in the future I think we
should make it required, rather than allowing a null config to be specified.
