1598657 - Make DB parameters for treeherder-dev similar to treeherder-stage

[Armen [:armenzg]]

Currently these are the innodb_ differences between the three:

Parameter	Production	Stage	Dev
innodb_io_capacity_max	5000	5000	2500
innodb_lru_scan_depth	256	256	256
innodb_log_file_size	17179869184 (16GB)	17179869184 (16GB)	8589934592 (8GB)
innodb_read_io_threads	8	8	4
innodb_write_io_threads	8	8	4
innodb_buffer_pool_size	48318382080 (45GB)	11811160064 (11GB)	11811160064 (11GB)

We need to bring treeherder-dev closer to treeherder-stage since they have the same DB size, storage type & EC2 instance type.

Specifically, I want to change innodb_io_capacity_max, innodb_log_file_size, innodb_read_io_threads & innodb_write_io_threads.

This is assuming that New Relic shows that treeherder-stage is better performant.

Parameter|Production|Stage/Dev
-----------|-------------|------|----
innodb_io_capacity_max|5000|same
innodb_lru_scan_depth|256|same
innodb_log_file_size|17179869184 (16GB)|same
innodb_read_io_threads|8|same
innodb_write_io_threads|8|same
innodb_buffer_pool_size|48318382080 (45GB)|11811160064 (11GB)

bobm, what are your thoughts?

If you need to I have added a comment in here and there are 3 attachments with the innodb_ values for each.
