Metainfo needs to know rate and burst limit to be able to limit users
requests. We made cache for per project limiter but to make single
instance we need to know about limits. So far we were doing direct DB
call to get rate/burst limit for project but it's generating lots of
DB requests and can be easily cached as we even have project limit cache.
This change extends project limit cache with rate/burst limit and starts
using this change while creating project limiter instance for metainfo.
Because data size kept in project limit cache is quite small this change
also bumps a bit default capacity of the cache.
