- while upgrading a host, throw a HOST_OFFLINE ("Server could not be contacted") exception if the host can no longer be resolved (instead of HANDLE_INVALID)
- also corrected the parameters of the HANDLE_INVALID exception, as an extra parameter is needed for the friendly error name.
- in the UpdateManualHostPlanAction class I replaced Host with the private property _host in several places, so we are no longer trying to resolve the host each time we want to write something into logs
- added some null checks, to avoid reporting null reference exception

been previously upgraded.
Introduced Host.LongProductVersion property which returns host's
product version and build number (e.g. 5.6.100.72258), or null if
product version can't be found. We use this property to check
if the master has been updraded and to decide which slaves need
to be upgraded or to skip hosts already upgraded.
