support mfa_serial by prompting for a token

[mullermp]

if you specify mfa_token in your config, then we set the serial_number param when creating an AssumeRoleCredentials: https://github.com/aws/aws-sdk-ruby/blob/master/gems/aws-sdk-core/lib/aws-sdk-core/shared_config.rb#L219

In the provider we will pass that to assume_role (https://github.com/aws/aws-sdk-ruby/blob/master/gems/aws-sdk-core/lib/aws-sdk-core/assume_role_credentials.rb#L51)

documentation: https://docs.aws.amazon.com/sdk-for-ruby/v3/api/Aws/STS/Client.html#assume_role-instance_method

If we pass serial_number than we also need to pass the token_code (which is a time based OTP generated by the device)
