    Http 400 when project enabled is not a boolean

    Having enabled="true" in json data when updating tenant will produce 500

    When updating a project, no type check was performed on the enabled
    attribute. Therefore, if enabled value in JSON/XML is not a boolean but
    a string, keystone responds with an incorrect Http 500 error code and
    the stacktrace.

    The change introduces a type validation of the enabled attribute at
    identity manager. If the type is not a boolean, keystone now returns an
    appropriate Http 400 error code with a message pointing a bad format for
    the attribute.

    Test cases have been added to file test_backend and test_content_types
    for testing the case when enabled attribute is a string or int when
    updating project.

    Fixes bug #1191384
