Allow multiple SSH keys per user

[pavlinpetkov]

Describe the Feature

Allow to assign multiple SSH keys per user account.
Currently only a single SSH keys is allowed via the public_key parameter of sftp_users variable.

Expected Behavior

Expected to be possible to configure multiple public keys per user.

Use Case

We have a location where there are 2 different parties interacting. One is uploading a resource to the SFTP S3 location, the other is consuming it.
Because these are 2 independent parties they generate their own SSH key pairs, not sharing their private keys.
it should be possible to set a user with two public keys for access so that both parties have access to the same user directory.

Describe Ideal Solution

Single aws_transfer_user resource with multiple aws_transfer_ssh_key resources.

Looks like a PR exists for this #33

We have the same use case so this module is not usable for us until this gets in. Any update on this?

Is there any way to add multiple keys to a single user via terraform.
