test / runner: new test for runSoftwareWithLock and runInstanceWithLock, which are both base functions of the webrunner

This also makes the function easier to test

  Now people can easily add tests

  slapos/builder was removed.

It's not needed anymore to create a user at first launch of webrunner. Credential can be created from slapos recipe directly.
Webrunner can also clone default repository at first launch.

/reviewed-on nexedi/slapos.toolbox!7

  Also don't interrupt of parse command output fails

the process if older than dependency set.

add is-process-older-than-dependency-set script

I was waiting for my instance to be built to test it, but still not ready.

So during the build, please @vpelletier, can you review this merge request?


See merge request !4

It was missing from the previous releases.

  Retry if git command fail (to fetch for example) and also retry if slapos report a connection error

  There is no need to be faster them 2 minutes between the queries.
