KUDU-3097 whether master load deleted table info could be configurable

When deleting table, the records in master tablet are just marked as
deleted, and all the table structure of table and tablet id are kept in the master
tablet forever.

From the perspective of storage, it's not big deal.
But it result in heavy burden if too many tables were deleted in past time.
By the way, msater only have one tablet and only leader works in
cluster, it would lead to imbalance memory usage.

This commit make it configurable to load those things into memory.
