a97cffcd52 connector/saml: refactor tests and add self-signed responses
Introduces SAML tests which execute full response processing and
compare user attributes. tesdata now includes a full, self-signed
CA and documents signed using xmlsec1.

Adds deprication notices to existing tests, but don't remove them
since they still provide coverage.

e0709dc2ac connector/saml: fix validation bug with multiple Assertion elements
When a SAML response provided multiple Assertion elements, only the
first one is checked for a valid signature. If the Assertion is
verified, the original Assertion is removed and the canonicalized
version is prepended to the Response. However, if there were
multiple assertions, the second assertion could end up first in the
list of Assertions, even if it was unsigned.

For example this:

    <Response>
      <!--
         Response unsigned. According to SAML spec must check
         assertion signature.
      -->
      <Assertion>
        <Signature>
          <!-- Correrctly signed assertion -->
        </Signature>
      </Assertion>

      <Assertion>
        <!-- Unsigned assertion inserted by attacker-->
      </Assertion>
    </Response>

could be verified then re-ordered to the following:

    <Response>
      <!--
         Response unsigned. According to SAML spec must check
         assertion signature.
      -->
      <Assertion>
        <!-- Unsigned assertion inserted by attacker-->
      </Assertion>

      <Assertion>
        <!-- Canonicalized, correrctly signed assertion -->
      </Assertion>
    </Response>

Fix this by removing all unverified child elements of the Response,
not just the original assertion.

e46f2ebe40 Improve SAML Signature and Response Validation
* Improve Order of Namespace Declarations and Attributes in Canonical XML. This is related to an issue in goxmldsig for which I created an [pull request](https://github.com/russellhaering/goxmldsig/pull/17).
* Do not compress the AuthnRequest if `HTTP-POST` binding is used.
* SAML Response is valid if the Message and/or the Assertion is signed.
* Add `AssertionConsumerServiceURL` to `AuthnRequest`
* Validate Status on the Response
* Validate Conditions on the Assertion
* Validation SubjectConfirmation on the Subject

aa7f304bc1 *: switch to github.com/ghodss/yaml for more consistent YAML parsing
ghodss/yaml converts from YAML to JSON before attempting to unmarshal.
This allows us to:

* Get the correct behavor when decoding base64'd []byte slices.
* Use *json.RawMessage.
* Not have to support extravagant YAML features.
* Let our structs use `json:` tags

57a59d4631 *: don't error out if a username doesn't exist in the backing connector
Instead of throwing a 500 error if a user enters an invalid name,
display the same text box as if the user had entered the wrong
password.

NOTE: An invalid username now returns much quicker than an invalid
password. Consider adding an arbitrary sleep in the future if we
care about masking which was invalid.

a3235d022a *: verify "state" field before passing request to callback connectors
Let the server handle the state token instead of the connector. As a
result it can throw out bad requests earlier. It can also use that
token to determine which connector was used to generate the request
allowing all connectors to share the same callback URL.

Callbacks now all look like:

    https://dex.example.com/callback

Instead of:

    https://dex.example.com/callback/(connector id)

Even when multiple connectors are being used.

Since we don't have a good strategy which takes a username and password
add a mock connector which implementes PasswordConnector so we can
