Allow using the SSH provider with my own OIDC provider instead of forcing identities

[hongkongkiwi]

Feature description

Having to use Infisical identities (or users) to login to the SSH features is quite limiting. That means your paying $18 per person which is a high price compared to other solutions or simply rolling your own.

It would be great if we can use Infisical with one user to set it up (on a paid plan), however use another provider such as Google for the actual authentication portion. This would be a fantastic feature!

Why would it be useful?

Would make this better for non-enterprise users with big budgets.
