docs: rewrite hvsupport.html page generator in python
As part of a goal to eliminate Perl from libvirt build tools, rewrite the hvsupport.pl tool in Python. This was a straight conversion, manually going line-by-line to change the syntax from Perl to Python. Thus the overall structure of the file and approach is the same. The new impl generates byte-for-byte identical output to the old impl. Tested-by: Cole Robinson <crobinso@redhat.com> Reviewed-by: Cole Robinson <crobinso@redhat.com> Signed-off-by: Daniel P. Berrangé <berrange@redhat.com>
