+(BKR-1058) Implement a simpler monolithic install method
+
+Currently, the `do_install` method is a mega-method responsible for
+installing and upgrading every version, layout, and platform of PE. It
+knows how to handle masterless installs, legacy agent installs, and
+extremely old versions of PE. Because of that legacy, it has some
+inefficiencies and is inflexible.
+
+Since the most common case by far is a simple monolithic or split PE
+install with a set of frictionless agents, we can dramatically simplify
+and therefore speed up the basic case. This commit implements a
+determine_install_type method that will detect whether the task being
+asked of it is one of those simple cases. The `do_install` method now
+branches based on the type of install, calling
+`simple_monolithic_install` for a basic monolithic + agents install, or
+`generic_install` for everything else. Simple split installs are
+currently detected, but not handled specially (they still fall back to
+the generic install).
+
+Doing away with some of the legacy concerns allows this method to be
+much simpler and more efficient. In particular, because the method has a
+defined task (mono master + agents, rather than a generic list of
+hosts), it can be optimized around that task. This is accomplished now
+by first installing the master, and then installing all the agents in
+parallel. This method also removes an extra agent run that hasn't been
+necessary since PE 3.3.
+
+For a monolithic master with four frictionless agents, this new method
+takes ~6 min 30 sec, compared to ~11 minutes before.
