New releases of oslo.config support a 'mutable' parameter to Opts.
This is only respected when the new method mutate_config_files is
called instead of reload_config_files. Masakari delegates making
this call to oslo.service, so how do we switch?
Icec3e664f3fe72614e373b2938e8dee53cf8bc5e allows services to tell
oslo.service they want mutate_config_files to be called by passing a
parameter, which this patch does.
This allows Masakari to benefit from
I1e7a69de169cc85f4c09954b2f46ce2da7106d90, where the 'debug' option
(owned by oslo.log) is made mutable. We should be able to turn debug
logging on and off by changing the config and sending SIGHUP.
Also in this patch configuration parameter
'retry_notification_new_status_interval' is marked as mutable.
