Make Moodle Operator timeout value configurable

Moodle Operator should implement timeout for deploying Moodle Pod.

Place to add in the waitForPod function:
https://github.com/cloud-ark/kubeplus-operators/blob/master/moodle/moodle.go#L791

Currently it is hardcoded as TIMEOUT_COUNT variable.

The timeout value should be made configurable. Can we use Helm chart's values to pass in this value?
