Remove the direct dependency to protobuf

[FlorentClarret]

What does this PR do?

Remove the direct dependency to protobuf

Motivation

protobuf is used for the prometheus check and thus should be declared in the base check only. There's no need to duplicate the dependency in other integrations since they depend on the base check.

Additional Notes

I found this trying to bump protobuf, I'll do that in a follow-up PR.

Review checklist (to be filled by reviewers)

• Feature or bugfix MUST have appropriate tests (unit, integration, e2e)
• Changelog entries must be created for modifications to shipped code
• Add the qa/skip-qa label if the PR doesn't need to be tested during QA.
