[CCSDK-1985]GR Toolkit Refactor

Refactor of the GR Toolkit provider module to allow for more
flexibility for different architectures. Health checking and
failover logic has been extracted into an abstract HealthResolver
class and several implementations for Single, Three, and Six
node controller architectures. Resolvers can be specified in
the gr-toolkit.properties file, or a fallback resolver can be
used if one is not specified.
