FEDORA-2016-687e3babd0 — enhancement update for copr-backend

obsolete

FEDORA-2016-687e3babd0 created by clime 8 years ago for Fedora 24

wrap feedback about actions to frontend into try-except
log even the traceback from forking
use makedirs instead of mkpath in fork action
if anything bad happens, log exception in generate_gpg_key action
also restart copr-backend-vmm and copr-backend-log when (re)installing
Bug 1361344 - RFE: Allow denial of build deletion and resubmitting at project or group level
catch errors in fork action
set action result for comps.xml and module_md.yaml file deletion
backend fork action now takes care of new gpg-key generation instead of frontend
removed no longer supported --api-version=0.8 arg from appstream-builder command line
specify module_md as module type
fix saving comps.xml and module_md.yaml into empty copr (with no build)
module_md.yaml is added to repodata now similarly to appstream.xml
support for generation of module dist tags
module_md.yaml uploading for a chroot
simplified build and action task workflow
use copy of the mock (chroot) config, not the original in /etc/mock/
