FS-11693 [core] Added switch_channel_set_log_tag() and switch_channel_get_log_tags() This allows you to add log tags to an active call channel. If using SWITCH_CHANNEL_SESSION_LOG, with switch_log_printf(), the tags will be added to the the log node so a logging module can send additional contextual data to a log aggregator.
