Unfinished test
(test_18_checkConfigurationGenerationERP5ScalabilityDistributor) uses
return value of subscribeNode and assumes it is ERP5 object.

This work changes return value of subscribeNode to JSON object,
following startTestSuite return value, thus rendering this test failure.

As test is unfinished, non asserting part has been commented out.

Also if process_timeout is available in received configuration setup
process_manager with transmitted value.

Backward compatibility is assured, that if no process_timeout is
provided, nothing is being updated.

Also process_timeout not set on master (the default), will not change
local default.

Extend subscribeNode to send configuration provided by user.

ERP5ProjectUnitTestDistributor allows to define maximum process timeout
of testnodes attached to it.

Spotted by chance. Seems unlikely to be hit, but that would be a stupid
arbitrary limitation nevertheless.

ComplexQuery bypasses SearchKey mechanism and makes assumptions
SQLCatalog.{search|count}Results does not do.
Instead, reserve a name, and complain if it is passed by caller.

"query" argument is not supposed to be different from any other
argument (argument name is [pseudo-]column name, unknown coluns are
rejected, and "None" means "IS NULL" SQL comparison), but is accidentally
special-cased in ERP5Catalog. This special-casing is to be removed, so
update all callers relying on this glitch.
Also, avoid using Query.

Also, do not use deprecated parameter name to pass a logical operator.
