This changes the ironic (ironic-api and ironic-conductor) services so that when a SIGHUP signal is issued, the service reloads (and uses) the values of mutable configuration options. The mutable configuration options (set by oslo.config Opts' mutable=True) are: - [DEFAULT]/pin_release_version - [DEFAULT]/debug - [DEFAULT]/log_config_append and are indicated as such in ironic's sample config (https://docs.openstack.org/ironic/latest/configuration/sample-config.html) by "# Note: This option can be changed without restarting.". Configuration options are mutable if their oslo.config Opt's mutable=True is set. This mutable setting is respected when the oslo method mutate_config_files is called instead of reload_config_files. Icec3e664f3fe72614e373b2938e8dee53cf8bc5e allows services to tell oslo.service they want mutate_config_files to be called by specifying the 'restart_method=mutate' parameter, which this patch does.
