slaprunner: Add a backup signature using sha256sum
slaprunner: Add a backup signature using sha256sum
Resilience: Increase timeout for ssh server and client to 5 minutes.
slaprunner: use LC_ALL=en_US in import/export scripts

pbs: enforce LC_ALL=C (importer/exporter as well) for proper sort collation

to mark the purpose, repeat inside the call to /usr/bin/sort,
but it's also needed for messages (i.e. we don't want /bin/cp
to write unicode chars in the pubsub feed)
pbs signature check: only sort by filenames, test for initial backup
pbs: refactored, use template for push_raw, quote with shlex for security

Conflicts:
	slapos/recipe/pbs.py
pbs: preliminary support for transaction-id
pbs: repeat pull loop until succeeded
resiliency: publish all feed URLs
slaprunner: don't backup sockets
rdiff-backup component: build 1.3.4nxd2
added --fix-corrupted argument to pull_raw
kvm, slaprunner: use toolbox 0.40.4 and rdiff-backup 1.3.4nxd2
kvm: converted templates to jinja2
develop to test rdiff-wip branch
