[PATCH v1 0/4] node and inheritance improvements

["Juraj Linkeš" <juraj.linkes@pantheon.tech>]

There are two areas that are unified:
The super() calls, where the arguments were removed as they're not
needed in single inheritance.
The classes derived from object don't need to explicitly state that.

The tg node execution setup and teardown was omitted and is fixed in
this series.

And probably the most important part if the cleanup of execution and
build target setup and teardown. Build targets are relevant only for sut
nodes, so it's been moved there, same for vdevs. The execution
setup/teardown code was modified so that subclasses use super() to
extend the base methods.

Juraj Linkeš (4):
  dts: add tg node execution setup and teardown
  dts: unify class inheritance from object
  dts: unify super calls
  dts: refine pre-test setup and teardown steps
