## What is the purpose of the pull request
Adding virtual keys support for Metadata table
## Brief change log
- Metadata table today has virtual keys disabled, thereby populating the
metafields
for each record written out and increasing the overall storage space used.
Hereby
adding virtual keys support for metadata table so that metafields are
disabled
for metadata table records.
- HFile data blocks written out and read back assume the record key and
partition
path metafields are always available. After turning on the virtual keys,
since
these metafields are not available, added support for HFile/Avro data block
readers, scanners to look at the table set record key property instead of
the
hardcoded metafield record key.
