Make the osd_*_sleep options modifiable during runtime and add them
to the set of tracked conf keys. This is to ensure that the sleep
options can be disabled/overridden during OSD bring-up if mclock
scheduler is employed.
Introduce OSD::maybe_override_options_for_qos():
This method does the following if the mclock scheduler is enabled:
- overrides the "recovery_max_active" to a high limit of 1000,
- overrides "osd_max_backfills" option to a high limit of 1000 and
sets the corresponding Async local and remote reserver objects also
to the same value (1000),
- disables osd_*_sleep options so that appropriate QoS may be
provided with the mclock scheduler.
The above method is called in the following scenarios:
- After all the op shards are brought up during OSD initialization.
- In OSD::handle_conf_change() to override any settings related to
QoS that the user intended to change.
Modify the mclock config reference to accurately reflect what options
can be changed when using mclock's "custom" profile and clean up
some whitespaces.
