Bug 1321144

Description of problem:

- In the Ceph configuration Guide (https://access.redhat.com/documentation/en/red-hat-ceph-storage/version-1.3/configuration-guide/#scrubbing) chapter 6.3 on Scrubbing details the following:

osd scrub begin hour

Description
    The earliest hour scrubbing can begin. Used with osd scrub end hour to define a scrubbing time window. Allows constraining scrubbing to off-peak hours. Takes an integer to specify the hour on a 24 hour cycle where 0 represents the hour from 12:01 a.m. to 1:00 a.m., 13 represents the hour from 1:01pm-2:00 p.m., etc. 
Type
    32-bit Integer 
Default
    0 for 12:01-1:00 a.m. 





osd scrub end hour

Description
    The latest hour scrubbing can begin. Used with osd scrub begin hour to define a scrubbing time window. Allows constraining scrubbing to off-peak hours. Takes an integer to specify the hour on a 24 hour cycle where 0 represents the hour from 12:01 a.m. to 1:00 a.m., 13 represents the hour from 1:01pm-2:00 p.m., etc. The end hour must be greater than the begin hour. 
Type
    32-bit Integer 
Default
    24 for 11:01pm-12:00 a.m. 






- This does not detail if scrub or deep-scrub is impacted here. This should be stated clearer that BOTH scrub and deep-scrub are impacted by this configuration setting.

For example could write up as:

osd scrub begin hour

Description
    The earliest hour that scrubbing and deep-scrubbing can begin. Used with osd scrub end hour to define a scrubbing time window. Allows constraining scrubbing to off-peak hours. Takes an integer to specify the hour on a 24 hour cycle where 0 represents the hour from 12:01 a.m. to 1:00 a.m., 13 represents the hour from 1:01pm-2:00 p.m., etc.
