As part of an goal to eliminate Perl from libvirt build tools, rewrite the augeas-gentest.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 use of $(AUG_GENTEST) as a dependancy in the makefiles needed
s/dependancy/dependency/
to be fixed, because this was assumed to be the filename of the script, but is in fact a full shell command line.
This is the case regardless of the Perl->Python conversion and can be done upfront to reduce the churn in this patch. Introduced by commit fb59cf7a5824b9c876737dcbf6aac97c29b1444a

Since this is a new file with clean history, it might actually deserve a better location than build-aux and we can leave this directory to Automake and gnulib to do whatever magic they do there. Also note that the directory is in .gitignore. (I added the exception for .pl files back when I added files here) Would 'scripts' be too vague? Could be a good place to put the helper scripts for generating QEMU caps files since I never seem to remember its name and tests/ is growing quite big. [...]

This uses three spaces instead of two like the original Perl script. Three match the rest of the .aug files, but by including that change here, this rewrite generates a different output.
