ureport: provide default URLs

We have two general use cases:
1. Completely anonymous uReporting
2. Authenticated uReporting

For good security reasons, we have to use a standalone server for each
of these use cases and this requirement complicates the configuration.
Users would have to change two options to switch between these two
configurations.

The configuration can be simplified by providing default URL for both of
them and single out the URL according to state of the "SSLClientAuth"
configuration option.

1. Completely anonymous uReporting
  - empty "SSLClientAuth"

2. Authenticated uReporting
  - "rhsm" or "rhsm-entitlement" in "SSLClientAuth"

ureport: include AuthDataItems if SSLClientAuth is configured

Forcing users to configure more than one configuration option to enable
Authenticated uReporting isn't good idea. So for sake of simplicity
reporter-ureport will add the AuthDataItems in to an uReport by default
if the SSLClientAuth is set to some value. Putting 'no' to the
IncludeAuthData configuration option, stops reporter-ureport from
including the AuthDataItems in uReports.
