feat(lambda-promtail): build lambda with zip file

[maxforasteiro]

What this PR does / why we need it:
Avoid having to create ECRs repos and building image with terraform instead.

Which issue(s) this PR fixes:
Fixes #

Special notes for your reviewer:
This is my first contribution. Let me know if there's anything else I can do to get this pushed to main. Our idea is to use tools/lambda-promtail as a module from our IaC without any extra steps. We have already implemented and tested a similar solution in our IaC and it works.

Checklist

• Reviewed the CONTRIBUTING.md guide (required)

Hey @maxforasteiro . There are a lot of users who already use lamda promatail in the way it was before.
could you change your implementation to support both schenarious?
I mean to leave it possible to use the link to the image in GCR or upload the archive directly....

Hey @vlad-diachenko, thanks for the quick code review! I just added the ability to either pass the image tag or generate it from the repo itself if it is absent.
