### Added support for PERFORMANCE_SCHEMA metrics
If Performance_schema is enabled you will get the following metrics as well.

Number of connections per Account (host-user) - Total and current
Number of connections per User - Total and current
Number of connections per Host - Total and current
Number of rows read per index - schema, table, index name, rows read
Indexes not being used (didn't get any read) - schema, table, index_name
Queries that raised errors/warnings - Query, number of executions, errors, warnings
Slow queries - Query, number of executions, execution time (total,max,avg), rows sent (total, avg), scanned rows
Added slow queries excluding table names. Very useful when you have different table with same 'schema'.
