* The solution libraries do not need a config file like the applications.
In fact the config file of XenAdminTests was mostly an unneeded copy of the
XenAdmin app.config; the NUnit setting has moved to the AssemblyInfo in NUnit3.
* Removed unused XenOvfApi settings.
* The constants in the Settings were largely not configurable, hence I moved them into the code.
The ones marked with TODO will be revisited within CP-32779.
* Removed config file from library XenOvfApi. Restored broken cryptography algorithm lookup.
(The list of algorithms had been removed from the Settings within the fix to CA-350574).
