CI | Data Buckets | Test AWS SDK Clients

[shirady]

Explain the changes

1. Add to the CI a test that runs basic commands using the most updated AWS SDK client. In this PR it is AWS SDK Go V2 as a start.
   Note: In this PR the CI runs on push and pull_request only in the code review phase, later it will be nightly and manual only (uncomment in current file).
2. Add log printings of 'pools_to_create.length' in coretest (helps in debugging in case the nodes/hosts were not created).

Issues:

1. The go script and its test were described in PR Add AWS SDK Go V2 Packages and a Test Script Using It  noobaa-operator#1521 and the need for having a CI that runs with most updated SDK version was raised as a part of PR FIx Request Handling on Requests with Trailing Headers (Mainly in ChunkedContentDecoder) #8753 to help us know of major changes in the AWS client behavior.

GAP - we need to create a CI to keep the update the packages in the code - to update the go.mod and go.sum files (currently it is manual).

Testing Instructions:

1. Run: make test-aws-sdk-clients
