Used to access directly to VM.

Also deploy takeover script only in import instances. This is non-sense to deploy it on export/pbs instances.

It will be used by equeue to prevent to run import scripts if detected.
Reason: if an import script is run AFTER takeover has been done, it may be stopped during its execution while slapgrid is run, causing the new-main instance not to behave correclty.

In case of erp5testnode, we have only one IP. So slapos node instance on clone instance would reach... slapproxy of main slaprunner.
