Change to existing monitor

🔖 Feature description

If someone were to perform a query such as "dig domain.com txt", there could be one to many results. The current mechanism for this checks just verifies that there is a return, but does not have the ability to monitor of an expected result. For example, if I wanted to make sure my SPF record hasn't changed, I could monitor for:

"v=spf1 include:mailserver.com ~all"

If that result doesn't match (e.g. changed, deleted), then it would alert.

✔️ Solution

Include a field / option to monitor for an expected result, similar as to the "HTTP(s) - Keyword".

As well, this should not just apply to TXT records. It would be equally important for A, AAAA, MX, SOA, etc.

Checking the content of dns queries is tracked in #432 and the PR to resolve this will be #3919, but it will be a while before it gets implemented.
