James Li f40681c3df Improve performance of recordsets API 
The performance of /v2/recordsets API was found slow when
filtering on large amount of recordsets. The patch proposes
the following ways to improve the performance,
and was tested with 1M recordsets.

1. To explicitly mention a correct table index in sql queries
for different sort keys and filtering keys.
We found mysql optimizer is not able to choose the most suitable index;

2. Introduce a new header 'OpenStack-DNS-Hide-Counts' to give operators
the flexibility of showing total_count or not, because we found that
the count query does not scale well on a large amount of records.

Performance results are at: https://gist.github.com/jamesyli/2eb9fb474a493477a9beb42fe122180f
