[ISC-support #18552] Logging category for notify/xfer related messages
Description
Logging category for notify/xfer related messages
Request
The notify category does not include some messages that end up in the general category. There are also some messages that might be better placed in xfer-in. For instance, "notify from" and "refused notify from non-master". The intent is to have all messages useful for troubleshooting an aspect of operation in one log. For example, if troubleshooting zone transfer issues, the relevant messages would be in the transfer.log. This segregation also facilitates some noise reduction when using dynamic severity.
