feat: ansible e2e tests

[camilamacedo86]

Description of the change:

• Port the ansible-e2e test to Go
• Add new tests to ensure that ansible projects have been covered

Note that:

• the mock Memcached example still the same but is generated (so we have no longer the need to keep static mock files to replace the content)
• its is adding tests to ensure OLM features and run local
• It ensures the metrics
• now we are creating the Memcached in an ns that is not the same as the operator to ensure that the cluster scope is working as should be.

Motivation for the change:

• Keep all tests following the same standard and increase the maintenance ability
• Ensure that the makefile targets are working since we are calling them
• Ensure that we are testing the changes performed since no longer static data is used.

Seems weird to effectively write a script in go but I understand the goal. So +1.

iuno, I'd rather read the output of a go program blowing up than have to debug a 100+ line bash script blowing up
