feat: add user_policy_document parameter @dod38fr (#142)
what
This parameter allows the user to specify policies that are applied to the S3 bucket with the policies defined by this module.
why
We want to add policies that forbid non admin users to access the bucket containing tfstates.
This commit allow us to specify a policy that implement these restriction without clobbering the policies put in place by this module.
Note that I have no problem to change the name of this new parameter if you want another.
