'tree_variants' in configuration should be able to limit the tree
variants, just like the config option 'tree_arches' which is used to
limited the arches.
For example, if there is configuration (refer to doc/configuration.rst)
go with:
tree_variants = ["Server"]
then only "Server" variants will be composed, and any other variants in
variants.xml will be ignored.
