Add readyness checkers to connectors

[eawagner]

Is your feature request related to a problem?

Not particularly but the connectors kind of trash waiting for the server to come on.

Describe the solution you'd like

Basically add a readyness check similar to the worker pods that waits until the server comes online (or atleast an option in the values.yaml to opt in).

Describe alternatives you've considered

Nothing really, a readyness check will just allow things to be more consistent with how the workers behave.

You can configure now your connector with readyChecker like worker on 1.3.2 version:

connector: []
  ...
+  # -- Enable or disable ready-checker waiting server is ready
+  readyChecker:
+    enabled: true
+    # -- Number of retries before giving up
+    retries: 30
+    # -- Timeout for each check
+    timeout: 5
  ...
