    CLOUDSTACK-8457: SAML auth plugin improvements for production usage
    * Move config options to SAML plugin
      This moves all configuration options from to SAML auth manager. This
      allows us to use the config framework.
    * Make SAML2UserAuthenticator validate SAML token in httprequest
    * Make logout API use ConfigKeys defined in saml auth manager
    * Before doing SAML auth, cleanup local states and cookies
    * Fix configurations in 4.5.1 to 4.5.2 upgrade path
    * Fail if idp has no sso URL defined
    * Add a default set of SAML SP cert for testing purposes
      Now to enable and use saml, one needs to do a deploydb-saml after doing a deploydb
    - CLOUDSTACK-8458:
        * On UI show dropdown list of discovered IdPs
        * Support SAML Federation, where there may be more than one IdP
            - New datastructure to hold metadata of SP or IdP
            - Recursive processing of IdP metadata
            - Fix login/logout APIs to get new interface and metadata data structure
            - Add org/contact information to metadata
            - Add new API: listIdps that returns list of all discovered IdPs
            - Refactor and cleanup code and tests
    - CLOUDSTACK-8459:
        * Add HTTP-POST binding to SP metadata
        * Authn requests must use either HTTP POST/Artifact binding
    - CLOUDSTACK-8461:
        * Use unspecified x509 cert as a fallback encryption/signing key
          In case a IDP's metadata does not clearly say if their certificates need to be
          used as signing or encryption and we don't find that, fallback to use the
          unspecified key itself.
    - CLOUDSTACK-8462:
        * SAML Auth plugin should not do authorization
          This removes logic to create user if they don't exist. This strictly now
          assumes that users have been already created/imported/authorized by admins.
          As per SAML v2.0 spec section 4.1.2, the SP provider should create authn requests
          either HTTP POST or HTTP Artifact binding to transfer the message through a
          user agent (browser in our case). The use of HTTP Redirect was one of the reasons
          why this plugin failed to work for some IdP servers that enforce this.
        * Add new User Source
          By reusing the source field, we can find if a user has been SAML enabled or not.
          The limitation is that, once say a user is imported by LDAP and then SAML
          enabled - they won't be able to use LDAP for authentication
        * UI should allow users to pass in domain they want to log into
        * SAML users need to be authorized before they can authenticate
            - New column entity to track saml entity id for a user
            - Reusing source column to check if user is saml enabled or not
            - Add new source types, saml2 and saml2disabled
            - New table saml_token to solve the issue of multiple users across domains and
              to enforce security by tracking authn token and checking the samlresponse for
              the tokens
            - Implement API: authorizeSamlSso to enable/disable saml authentication for a
            - Stubs to implement saml token flushing/expiry
    - CLOUDSTACK-8463:
        * Use username attribute specified in global setting
          Use username attribute defined by admin from a global setting
          In case of encrypted assertion/attributes:
          - Decrypt them
          - Check signature if provided to check authenticity of message using IdP's
            public key and SP's private key
          - Loop through attributes to find the username
    - CLOUDSTACK-8538:
        * Add new global config for SAML request sig algorithm
    - CLOUDSTACK-8539:
        * Add metadata refresh timer task and token expiring
            - Fix domain path and save it to saml_tokens
            - Expire hour old saml tokens
            - Refresh metadata based on timer task
            - Fix unit tests
