Is your feature request related to a problem? Please describe.
the shell test is harder to keep maintained and is using mocks of data which is not updated with the changes in the PR which means that not necessary is covering the code changes.

Describe the solution you'd like

• Port the Ansible tests to be done in go
• Note that, the test of e2e-ansible.sh will are mainly be the same done for Helm: https://github.com/operator-framework/operator-sdk/tree/master/test/e2e-helm. It has some additional checks that would require to be added in the cluster test.

we have 2 directories that require to be replaced:

• test/ansible : It will be addressed in the issue: Replace the test/ansible static files by a mock data generated with the samples stack #4025
• test/molecule-operator: it is addressed in the PR: e2e tests: migrate the memcached molecule tests to use the new layout (1.0+) with mock samples stack #4011

So, since it is a bug scope we will close this one with the merge of #4011 to do the same for the advanced mocks which are in test/ansible via the issue #4025
