Bug 515668 - Introduce APIs to group MavenProject reads
Using ProjectBuilder.build(singlePom...) has a speed and memory
complexity of O(depth(project)) where depth(project) is the number of
parents (recursively). Iterating on this over N projects lead to a
pseudo-quadratic cost O(N*maxProjectDepth) where maxProjectDepth can be
up to N-1.
Instead, we introduce APIs that take advantage
ProjectBuilder.build(multiplePom...) which has a complexity of O(N).
For Apache Camel that is 700+ modules, these new APIs instantiate  700+
MavenProject instead of ~4000 (since many modules have a depth of 5/6)
like legacy API do.
