Use boto3 ec2.create_key_pair() function

[bisoldi]

Is there a reason you're using the python cryptography package to create the RSA key rather than using the boto3 create_key_pair function in the EC2 module?

Is it simply to allow customizing the keysize?

The secret provider is capable of generating several types of private keys, so for consistency I used the Python cryptography package.
