Add a test for go routine leaks
This is in its own separate package so that it will be a separate test binary that runs thus isolating the go runtime from other tests and allowing accurate go routine leak checking.

This test would ideally use goleak.VerifyTestMain but that will fail 100% of the time due to some architectural things (blocking queries and net/rpc uncancellability).

This test is not comprehensive. We should enable/exercise more features and more cluster configurations. However its a start.

Bump version of miekg/dns to 1.0.4
See https://github.com/hashicorp/consul/issues/3977

While trying to improve furthermore #3948 (This pull request is still valid since we are not using Compression to compute the result anyway).

I saw a strange behaviour of dns library.
Basically, msg.Len() and len(msg.Pack()) disagree on Message len.

Thus, calculation of DNS response is false consul relies on msg.Len() instead of the result of Pack()

This is linked to miekg/dns#453 and a fix has been provided with miekg/dns#454

Would it be possible to upgrade miekg/dns to a more recent function ?

Consul might for instance upgrade to a post 1.0 release such as https://github.com/miekg/dns/releases/tag/v1.0.4
