Allow masking of finding and provide reason without disabling the control

[chetanfni]

Additional context
I have a few instances where I want to mask a finding and do not want to disable the control.

Is your feature request related to a problem? Please describe.
While completing the compliance checks it is required by auditor to review the maskings and comments as to why those are masked, for example we have an alternate solution for logging and want to provide that as a comment to auditor.

Describe the solution you'd like
I should be able to provide comments as to why am I masking the policy. Also, masking should have a date as to till when the policy should remain masked, can allow a user to mask indefinitely.

Describe alternatives you've considered
Currently I am managing masking comments via internal JIRA
