Because of breakage changes it is published under the new name
`ng-ebi-authorization`. Added a deprecation warning to the older
version.

feature: expose token through the user

See merge request tools-glue/angular-aap-auth!3

Exposing the token to other services is essential for correct usage
of jwt auth, to be able to authenticate requests against secured
services.

So we make it easier to use tokens

breakage: simplified and opinionated API

Closes #3

See merge request tools-glue/angular-aap-auth!2

Now we use `User` object instead of 'Credentials'.
The token is not exposed anymore through the auth, TokenService needs to
be used to access it.
Domains are not exposed for the time being as it can give a false sense
that checking domains in a web app is somehow accepted or even
recommended for security purposes, this is not the case.

feature: use sub instead of email as username

See merge request tools-glue/angular-aap-auth!1

Also exposed email as it can be of use for the webapps

Drop dependency to rxjs-compat

Because rxjs-tslint-rules detects both version 5 and 6 of rxjs it
complaints about wholesale imports.

After the jwt library is update, remove the rxjs-compat and revert back
the rule.
