[MNG-4633] Re-added configurable phase synchronization wrt upstream phase

Made execution plan calculation parallel in weave mode

Existing weave mode would only phase-lock to the same phase upstream.
Execution plan calculation made parallel at high-level, still looking
into reducing blocking in DefaultMavenPluginManager to cash in on this.
