Multiple testnode can concurrently run the same test, so create test
results only at the end to reduce the risk of race conditions on test
completion leading to tests never reported as completed.

This shows a limit of the current approach; switching to nxdtest
appears desirable.

Use runTestSuite interface to launch tests that request instance on
actual SlapOS cloud, using certificate passed as parameter.

Parameters are:
{
  'client.crt': <crt>,
  'client.key': <key>
  'master-url': <url>
}

Such a json of parameters can be generated from existing SlapOS client
configuration using the `generate_parameters` script.

The test currently requests a KVM and examines the connection dict as
a demo.

without this cleanup, the software integration tests of KVM were stuck
forever because unittest was waiting for the subprocess to stop.

if '-ltinfo', '-ltermcap' or '-lcurses' is set in the linker option,
sqlite3 binary wil link to system libtinfo like this:

if libuuid was present on the system, python would link with it in:
lib/python3.9/lib-dynload/_uuid.cpython-39-x86_64-linux-gnu.so

if libtinfo was present on the system, readline would prefer to use it instead of libncurses

This will let a non-shared Theia (for example coming from shacache
binary) to be able to use the shared parts of a machine.

Fix takoever of a theia with initial embedded instance. The issue was
that the promise checking that the embedded instance was successfully
requested relied on files which were not transferred to backup theia.

The location of these files has been changed in order to transfer them;
therefore the old location is still checked for upgrade-compatibility.

Test that takeover of theia with an initial embedded instance succeeds.

See merge request nexedi/slapos!1403

Now each partiton in slapos-sr-testing has its own IPv6 thanks to
ipv6 range, takeover url changes after takoever, so up-to-date
connection parameters need to be fetched before doing a second
takeover.
