feat: Pod impersonation

[lmouhib]

Is this a bug fix or adding new feature?
New feature

What is this PR about? / Why do we need it?
Add the ability for efs-csi-driver to impersonate pods.

Recreating #710 the previous one was closed and reverted after merge. Starting from new one instead of reverting.

What testing is done?
Tested with pods that have service account annotated with a role ARN. The efs-utils assume the role annotated to the service account and is able to mount an access point that is protected with an IAM resource policy.

Hi @lmouhib. Thanks for your PR.

I'm waiting for a kubernetes-sigs member to verify that this patch is reasonable to test. If it is, they should reply with /ok-to-test on its own line. Until that is done, I will not automatically test new commits in this PR, but the usual testing commands by org members will still work. Regular contributors should join the org to skip this step.

Once the patch is verified, the new status will be reflected by the ok-to-test label.

I understand the commands that are listed here.
