This implementation splits the execution and node configuration
components of the conf.yaml into two separate config files. A
new command line argument is added, allowing the user to specify
both a node configuration file and an execution configuration
file. Be default, these config files are now named node_conf.yaml and
execution_conf.yaml, respectively.
To assert these changes, the schema calls for one of these objects,
nodes or executions, in each file, but neither config file can have
both.
To avoid excess refactoring, both config files are merged together
early on in the load_config process.
Bugzilla ID: 1344
