CHANGE DESCRIPTION

Problem:
The patroni metrics were not available in PMM. Given that patroni runs in TLS mode, we need to utilize an option that was added on PMM3.3 that skips the tls verification. The auto generated certificates do not contain the localhost 127.0.0.1 in its Subject Alternative Names (SANs).

The related feature will not be available in PMM2.

Cause:
Short explanation of the root cause of the issue if applicable.

Solution:

The e2e test for pmm3 is updated to query a selected patroni metric to verify that the integration is done properly.

Also visible through the PMM dashboard:
