On python3 several views were not functional, because subprocess output was
retrieved as bytes, but manipulated as a string.

This adds a few tests for views, not complete because it would be too much time
consuming for now.

to

the behavior seems the same, default config in both cases is to trust one
level of proxy.

fixup for ecf144ee

current_project variable is mandatory

   The generation of the link and the verification were inconsistent, this commit
   normalize both.

   PS.: Software Links are deprecated, it should be removed in future, as it lost
   the goals

This is another fixup for commit
1c8269b2.

With slapos.core!125,
this is not the case anymore by default.

This commit does not nothing when using older slapproxy.

This shall be helpful when debugging why the data disappeared from a
webrunner.

[webrunner] when displaying connection parameters, sort them in alphabetical order (as done on slapos master)

I tested in my webrunner

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.

  Pin version of setuptools as >=34 don't work

  It means there is no extra test to run.

Revert "resiliencytest: adds tests on services status after takover for the slaprunner" and its fixup!

This reverts commit 26c5ef0b.
This reverts commit edc91312.

Revert "runner: if no "slapos-software" is defined in parameters, the auto build&run feature shouldn't work"

The current behavior should stay until a correct way of restarting processes in the webrunner (ie: watchdog within slapproxy) is implemented

This reverts commit 50948d5b.

It makes tests easiers and lighten the code in view.py

The code in the view is lighter, and the generic part could have been moved to utils

This also makes the function easier to test
