Google secrets manager integration synchronization

[davidhonig]

Feature description

We are thinking about using Infisical as central distribution system for secrets.

The feature is about creating an integration with GSM which takes a project/environment/path and synchronizes the secrets to the GSM, ideally I can use multiple integration to synchronize different directories to different GSMs.

Authentication should be based preferably on GCP SA json file

Why would it be useful?

For delivering secrets to different cloud projects and using Infisical as source of truth.

• It would be awesome to be able to sync more directories to same GSM (ie global secrets and specific secrets)
• It would be awesome to be able to combine it with AWS, Azure

Providing an update here that we've extended this integration to allow using service account JSON (SAJ) as an authentication method to sync secrets from Infisical to GCP Secret Manager as of #944.

This covers part if not all of this issue (will close this issue once you test it out and lmk if it works @davidhonig) 😄

An extension would be to allow users to add multiple authentication credentials to a single integration in Infisical. In the context of this integration, it would allow users to sync various folders to various GCP projects, each with its own SAJ if that is preferred.
