This promise will replace the old check_port_listening promise (https://lab.nexedi.com/nexedi/slapos/blob/master/slapos/recipe/check_port_listening.py). See https://www.erp5.com/slapos-TechnicalNote.General.SlapOS.Monitoring.Specifications for how to instantiate this promise in buildout.

Since slapos!a222ccfabc10103c6ecb9195de4e0c0250705d11, haproxy process name is variable,
so let's restart the full partition instead of guessing the name of the process.

This solve indefinite loop in while condition on promise check_free_disk_space

check_free_disk_space is now in promise.plugin, with some improvement.
Database connection timeout is now 10 seconds
If database is locked, promise will try again 10 times before start to raise error with "database is locked" message.

When the URL /isSRReady is called if the software release link is not present in softwareLink folder, webrunner will launch build of software. The result is slapgrid trying to build sr every minutes, then resiliency fail.

Start slapproxy at runner startup and when instance is removed in webrunner. This fix resiliency problem when proxy.db file does not exist.

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 will show the latest buildout logs.
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.
