TS runs out of FDs for WALs when running many tablets

      Description

      A user was recently complaining that his TS ran out of FDs when he had many tablets and that most were being used by WALs.

      While this was a bit of a non-usual setup - a lot of un-replicated tablets on a single TS - we're likely to hit this problem as we increase density and try and have many more tablets per tablet server.

      The report was that each tablet would use 3 fd's for the WAL. Ultimately we'll likely need some solution akin to the what we've done for the FBM/LBM regarding having an LRU cache of fds for the WAL too.
