* Add purpose and expiry support to `MessageVerifier` & `MessageEncryptor`.
Messages generated using `MessageVerifier` and `MessageEncryptor` now
support expiry and purpose. You can set the purpose of the message using
the key :purpose, and likewise, the expiration using :expires_at or :expires_in.
This ensures that the message is used only for its intended purpose and also
while it hasn't expired.
For instance, to ensure a message is only usable for one intended purpose:
token = @verifier.generate("x", purpose: :shipping)
@verifier.verified(token, purpose: :shipping) # => "x"
@verifier.verified(token) # => nil
Or make it expire after a set time:
@verifier.generate("x", expires_in: 1.month)
@verifier.generate("y", expires_at: Time.now.end_of_year)
Showcased with `ActiveSupport::MessageVerifier`, but works the same for
`ActiveSupport::MessageEncryptor`'s `encrypt_and_sign` and `decrypt_and_verify`.
