QEMU image build improvements

* Added missed package dependencies (for Debian 10 based builders)
* Added additional options, which can be passed to the playbook:
  * iso_local - path to local ISO file
  * disk_size - target disk image size
  * cloud_init - enable or disable Cloud-init integration to an image
  * cloud_init_ds - set custom list of data sources for Cloud-init
* Added a version number and Cloud-init mark to a QCOW2 image name
* Cloud-init installation procedure tuned to use packages from a proper one VyOS repository, according to VyOS and Debian version
* Added workaround for /etc/network/interfaces to allow Cloud-init initialize network in a native way
* Replaced default config file to Jinja2 template
* Fixed GRUB installation on UEFI builders - added target i386-pc
* Replaced GRUB configuration:
  * enable both KVM and Serial console for all images (Serial by default)
  * added password recovery option for all images
  * added 5 seconds of a timeout to allow select proper menu entry
  * fixed booting for 1.3 VyOS
* Added loop device detach after image build - allows to build images multiple times without exhausting loop device limit
* Added fstrim applying for image - theoretically, this may save some space
* Enabled compression for QCOW2 image - this reduces image size significantly
* Added RAW image deletion after conversion to more accurate cleanup
