This reverts commit b6f08b9e.

Because this promise is relaxed, it leads to situation, that slaves are not
prepared, and no more processing would be needed.

Most possibly much more advanced logic is required.

This revertion is created to store the finding.

The error is like:

FAIL: test_https_url (test.TestSlave)

validate_frontend_configuration is exactly check_command_execute, so just use
it.

Replace trafficserver_cache_availability with check_command_execute which
has the same functionality.

The eventual message from trafficserver_cache_availability will be visible
anyway.

publish-failsafe-error-promise and promise-key-download-url-ready shall be
less reactive, as otherwise it results with constant problems detection on
the running cluster, by raising tickets. When those promises are less
sensitive it gives time for the cluster to stabilize.

After dropping _force_slapos_node_instance_all tests with parameter propagation
need special treatment:

 * during first waitForInstance it is needed to wait for instance for the
   parameterto be requested to the master
 * during second waitForInstance the parameter is being propagated to other
   instances

This is solved by waitForInstanceWithPropagation

In some cases tests are modyfing in-place partitions (eg. .slapos-resource)
in order to mock some states. Then it's required to force instatiation with
waitForInstanceWithForce.

In other places additional, sometimes conditional, processing is added in
order to account for non forced default processing.

Do not force --all for instance in order to test real instantiation.

`maxSession` is a selenium node option

`slotQuantity` set the number of slots by node meaning the maximum number of
session for a node.

Otherwise promise won't fail even if frontend is not yet here
and partition will not be processed until next day when
a bang happens

  This is required to install lxml-python dependencies which is a
  sub dependency of jupyter

  This is a PoC to compile wendelin and slapos-master with python3, and
  specially to run the tests.
