  fixes.

   - convert perag to use xarrays

   - create a new generic allocation group structure

   - add metadata inode dir trees

   - create in-core rt allocation groups

   - persist quota options with the enw metadata dir tree

   - enable quota for RT volumes

   - enable metadata directory trees

   - some bugfixes"
