Extend logs and raise the D-Bus timeout

[imobachgs]

Problem

We are having a hard time finding out what is wrong in bsc#1214737. Although the D-Bus daemon is asking the software service to start, we do not see any trace of it (not even crashing).

Solution

In order to get more information:

• We are extending the amount of information in the logs (logging all installer phases and steps).
• The log includes now the service name ('manager', 'software', etc.).
• We have raised the D-Bus timeout limit, just in case the testing systems are taking more time for some reason.
