like `{<number>}` are replaced with the respective matches in the file name, e.g. `{1}` is the
first match, `{2}` is the second. The default is: `db\.(.*) {1}` i.e. from a file with the
name `db.example.com`, the extracted origin will be `example.com`.
**TIMEOUT** is deprecated and will be removed in a subsequent version.
`reload` will be used, if not defined
(it specifies how often CoreDNS should scan the directory to watch for file removal and addition;
the default is every 60 seconds. This value is in seconds. The minimum value is 1 second.)
* `reload` interval to perform reloads of zones if SOA version changes and zonefiles. Default is one minute.
* `transfer` enables zone transfers. It may be specified multiples times. `To` or `from` signals
the direction. **ADDRESS** must be denoted in CIDR notation (e.g., 127.0.0.1/32) or just as plain
addresses. The special wildcard `*` means: the entire internet (only valid for 'transfer to').
When an address is specified a notify message will be send whenever the zone is reloaded.
* `reload` interval to perform reloads of zones if SOA version changes and zonefiles. It specifies how often CoreDNS should scan the directory to watch for file removal and addition. Default is one minute.
Value of `0` means to not scan for changes and reload. eg. `30s` checks zonefile every 30 seconds
and reloads zone when serial changes.
* `no_reload` deprecated. Sets reload to 0.
* `upstream` defines upstream resolvers to be used resolve external names found (think CNAMEs)
pointing to external names. CoreDNS will resolve CNAMEs against itself.
