resiliency data in instance_root/slappart0/var/log/log.log is writen by a service in slaprunner, so after the takeover
the service will start again an write a new entry. We should then check if data from old runner0 is present in new data log.

Also set database connection timeout to 5 second

promise check_partition_deployment_state.py that buildout didn't fail to process the partition, if failed

the promise monitor_bootstrap_status.py is used to check monitor bootstrap is ok

promise are run by slapgrid now, monitor will collect result and generate final files
monitor runpromise script can be used to test a promise (which is implemented on the new promise design)
remove all generated script and logrotate code from monitor.py, they will be added in buildout

A promise that would check slapuser memory in collector.db (like check_computer_memory promise).

- API:
    - --threshold parameter (int, float)
    - --unit parameter (byte, percent)
    - --user parameter (e.g. slapuser9)

/reviewed-on nexedi/slapos.toolbox!30

Add the possibility to choose unit between byte or percent,
and to choose between checking used or free memory.

avoid to return exit code (int) or mem (object)
better return a tuple (mem, error_message) (object, str)

test_check_apachedex_result: also extract promise messages from test methods

test_check_apachedex_result: fix float threshold

remaning -> remaining

free were equal to memory_used
used were equal to memory_free

Allow to hotplug/hotunplug CPU and Memory in VM using qemu QMP client.
