1555426687 netwatch-notify: increase the timeout even more 
This interacts with the number of addresses in the address-list. Having
a lot of addresses there (for exemple from script 'fw-addr-lists' 😜)
makes the 'find' take longer. We have to make sure that 'find' succeeds
before the address times out.

As this does not hurt... Let's just bump to 10 seconds to be safe.

209c37664b netwatch-notify: do not switch type when resolving 
This requires RouterOS 7.15beta4, but let's bump the required version
to next stable release instead.

01d2c3ea7e netwatch-notify: try another workaround 
The last one did not make it... Perhaps the cache just needs

93bed1b081 netwatch-notify: work around race condition 
This used to crash every now and then with:

> script;error script error: no such item (4)

I guess this is caused by querying the dns cache just exactly when a
record expires. The chance is maximized: The script is started by
scheduler every minute, and the record's ttl is a multiple of a minute.

Let's query records that are not about to expire immediately, and
try again.

c2f5272f18 netwatch-notify: restore the check 🥴 
This reverts commit 28da1da49e275fef6089a103edf6c158bbff317f.

Chances are that we have to resolve a CNAME, that does not match when
querying the cache.

How to handle CNAME do multiple A records? 🤨

1344694708 netwatch-notify: handle status "down" in its own condition... 
... instead of else-branch.

This makes sure to skip hosts that just became "unknown".
(Possible soon!)

b286cb6803 netwatch-notify: do not update with record in cache 
Using `:resolve` we have just one address, but chances are several
records do exist. These end up in cache, so we are happy to find them
there - no need to update then.

eef0662aa7 netwatch-notify: allow to give different origin for hosts... 
... to use differing notification settings.

Add an origin name in netwatch configuration:

    /tool/netwatch/add comment="notify, name=dns-google, origin=netwatch-notify-google" address=8.8.8.8;
    /tool/netwatch/add comment="notify, name=dns-cloudflare, origin=netwatch-notify-cloudflare" address=1.1.1.1;

Then configure the notification settings in `global-config-overlay`:

    :global EmailGeneralToOverride {
      "netwatch-notify-google"="google@example.com";
      "netwatch-notify-cloudflare"="cloudflare@example.com";
    }

I think it is best to handle this as a hidden setting...
Handle with care!
