Requests an email verification token for the purposes of adding a third party identifier to an account. This API requests a token from the homeserver. The doesServerRequireIdServerParam() method can be used to determine if the server requires the id_server parameter to be provided. If an account with the given email address already exists and is associated with an account other than the one the user is authed as, it will either send an email to the address informing them of this or return M_THREEPID_IN_USE (which one is up to the homeserver).
