Added support for Veeam endpoint backup jobs to Windows agent plugin.

Example output of `Get-VBREPJob`:

```
RepositoryId : fa137044-0e1f-11e6-86b3-a77f5f0d70f0
ObjectsCount : 1
IsEnabled    : True
NextRun      : 26.09.2015 22:00:00
Target       : $target
Type         : EndpointBackup
LastResult   : Success
LastState    : Stopped
Id           : ef13e0b6-0e1f-11e6-842a-07b51a32dae7
Name         : Backup Job $hostname
Description  : Endpoint backup job
```

The `NextRun` value does not match the value shown in the Veeam GUI as
of Veeam 9.0.0.1491. This needs to be checked.
Compared to `Get-VBRJob`, `Get-VBRJob` does not seem to report job start
and stop times.
