add key_data argument to ec2_win_password.py module

[maxstack]

The key_data argument helps when using a private key stored in Vault.

SUMMARY

This PR relates to the AWS ec2_win_password.py module. We have a use case where we need to decrypt Windows passwords for ec2 instances, the existing module allows you to specify a file path to a private key. Our workspace is not persistent so the private key is not persistent to the filesystem, and we will not store it in SCM as Ansible Vault will not decrypt it on the fly.

I have added a new argument - key_data, to use as an alternative to key_file. You can store your private key in Ansible Vault and pass the variable (eg. "{{ ec2_private_key }}") to this argument for on the fly decryption.
