GEODE-8772: Pre-assign ports in the test JVM

[demery-pivotal]

Change ClusterStartupRule to assign ports only in the test JVM.

As part of my project to allow Geode tests to run in parallel outside of
Docker, I am changing our build system to allocate a distinct range of
ports to each test JVM, and changing AvailablePort and
AvailablePortHelper to honor these allocated port ranges.

This commit prepares for those changes.

Certain tests use ClusterStartupRule to start a member in a child VM
using a prior version of Geode. When such tests run in parallel outside
of Docker, the child VM can attempt to bind to ports that are in use by
tests in other JVMs.

When the ClusterStartupRule starts a member in a child VM, it does so
by creating the appropriate member starter rule (LocatorStarterRule or
ServerStarterRule) in the child VM. Depending on how this member
starter rule is configured, it may call AvailablePort in the child VM
to assign certain ports. The AvailablePort in the child VM is a prior
version that knows nothing of the port partitioning scheme I’m currently
adding, and so may assign ports from outside of the range of ports
allocated to test. These ports may conflict with ports already in use by
tests in other JVMs, or ports that are "reserved" by those tests.

Make tests assign ports only in the test JVM. The test JVM always
includes the latest implementations of AvailablePort and
AvailablePortHelper, and so the tests will honor any port allocation
scheme defined in the latest implementation.

• Change LocatorStarterRule, ServerStarterRule, and their common
  base class MemberStarterRule to pre-assign available ports in their
  constructors. They use AvailablePortHelper to assign the ports, and
  store the assigned port numbers as fields.
• Change ClusterStartupRule to construct any required member starter
  rules in the test JVM instead of in the child VM. As a result, the
  member starter rules call AvailablePort and AvailablePortHelper
  only in the test JVM, where (eventually) the implementation will honor
  the range of ports allocated to the JVM.
• When the ClusterStartupRule sends the member starter rule to the
  child VM, the member starter rule is deserialized in the child VM with
  the pre-assigned port numbers. If the member starter rule is
  configured to assign a port, it uses the one that was pre-assigned in
  the test JVM.
