[pve-devel] [PATCH v2 pve-container/qemu-server/pve-docs/pve-guest-common 0/8] Add pre/post-migrate hooks

This series adds pre/post-migrate hooks to the migration process of containers
and VMs.

Additionally to testing the API/CLI migration from updated nodes, I have also
made sure to keep backwards compatibility with old nodes. This means that
migration to a node that has not yet been upgraded to support the migration hook
functionality works flawlessly. The behaviour in this case is that a warning
is printed and the migration process then continues as usual.

Changes from v1:
- remove the newly added CLI commands
- remove the abstract methods from pve-guest-common
- Add migrate-hook and query-migrate-hook commands to qm mtunnel
- Add migrate-hook functionality to Qemu backend
- Add pct mtunnel command
- Add migrate-hook, query-migrate-hook and quit commands to pct mtunnel
- Add migrate-hook functionality to LXC backend
- Add documentation for migrate-hooks to VM Hookscript documentation
- Add section for Hookscripts to the Container documentation
- Extend exec_hookscript functionality to include run parameters for run_command
