Add DNS integration
Problem to solve
When the user doesn't have a monitoring solution and want a lightweight solution to make DNS checks.
Proposal
Add an DNS integration for updating monitors.
Monitors should have the integration
value set at dns
or dns_<SUFFIX>
and external_reference
should be specified.
The integration check that a DNS name have a record A
(any).
CNAME
record are followed until a A
is found
Integration possible configuration could be :
- Timeout
- DNS server (ip & port)
