[virt-manager] [PATCH v3 3/4] asyncjob: Add enable/update details methods

[Radostin Stoyanov <rstoyanov1@xxxxxxxxx>]

Add virtual terminal emulator (Vte) in which could be shown details
of background running process.

Usage example:

- To enable details:
> asyncjob.details_enable()

- To show text inside the Vte:
> asyncjob.details_update("Some text here")
