Add --disable-metrics flag

[spowelljr]

Fixes #13656

Problem:
Implemented #13189 which increased the housekeeping interval to help alleviate CPU usage. However, this has seemed to completely disable metrics reporting and we have been getting numerous reports such as #13620.

Solution:
Removed increasing the housekeeping interval by default. Added a --disable-metrics (false by default) flag which will increase the housekeeping interval again and disable the metrics reporting for people that want to do so for CPU usage improvements.
