My customer has multiple instance of graphAPI.
One of them is hosted in China and so has customized endpoints.
It would be nice to have these parameters customized in lsc.xml

I have listed these urls (may be non exhaustive):

in MsGraphApiAuthentication.java, the authentication URL:

        WebTarget authTarget = ClientBuilder.newClient()
            .register(JacksonFeature.class)
            .target("https://login.microsoftonline.com/")
            .path(tenant)
            .path("oauth2/v2.0/token");

in MsGraphApiDao.java, the users endpoint:

        usersClient = client
            .target("https://graph.microsoft.com")
            .path("v1.0")
            .path(USER_PATH);

For the moment, I only consider the need to have the FQDN customizable.
