Release version 2.1.0 for hex.pm

[hirocaster]

I think you should publish version 2.1.0 for hex.pm

ref #5

But, I don't have permission for hex.pm.

If you don't mind, can you release it? @benwilson512

memo: Don't forget to change README.md

def deps do
  [
    {:ex_aws, "~> 2.1"},
    {:ex_aws_kms, "~> 2.1"},
    {:poison, "~> 3.0"},
    {:hackney, "~> 1.9"},
  ]
end

[benwilson512]

Please send me your hex.pm username to [my github username] @gmail.com, and I'll add you to the project so you can do releases.

This is mine https://hex.pm/users/hirocaster
and I will send mail.

Send done.
