Switches to netinstall images instead of minimal

Other changes:

  - Adjusted packer configs to use MSVSphere 9 as a base platform
    for building images.
  - Added special notes on building images on Fedora.
  - Added instructions on debugging image build process.
  - Added vnc_port_min and vnc_port_max packer variables to make
    build on remote machines easier.
  - Updated Generic Cloud kickstart file to use public mirror
    instead of the internal one.
  - Updated Generic Cloud kickstart file to use "os" instead of
    "kickstart" repos in order to install all present updates.

+## Debugging image builds
+
+Use `PACKER_LOG=1` environment variable definition to get extra debug output
+from Packer:

+
+other Packer debugging techniques are described in the Packer
+[documentation](https://developer.hashicorp.com/packer/docs/debugging).
+
+Add `-vvvv` flag to the Ansible's `extra_arguments` block in a Packer config
+in order to get verbose output from Ansible:

+```hcl
+build {

+Additionally, you can connect to Packer's VNC session using a VNC client.
+For TigerVNC you will need to enable the following settings:
+
+* Input -> View only (ignore mouse and keyboard)
+* Misc -> Shared (don't disconnect other viewers)
+
+By default Packer is running a VNC server on a random TCP port in the
+5900:6000 range. But for remote build environments it might be useful
+to use a specific port so that you can configure a firewall easily:
+
+```shell
+$ packer build ... -var vnc_bind_address=0.0.0.0 -var vnc_port_min=5900 \
+      -var vnc_port_max=5900 .
