RunConfiguration.load() does not work

Hi

It appears the RunConfiguration.load() does not work. For example code snippit:
```
hdi_run_config = RunConfiguration()
hdi_run_config.load(path='.', name='hdi')
```
It finds the file - but after putting a debug point after the load, the object clearly isn't loaded with the hdi.runconfig, and is instead loaded with a default local.runconfig (which isn't in the project). In addition to this, after doing a exp.submit, it automatically creates a aml_config directory with docker.runconfig, local.runconfig, conda_dependencies.yml which is not related to what we doing (these are just templates anyway).

Start by reproducing the RunConfiguration.load(path='.', name='hdi') example and inspect the resulting configuration. Compare it with the hdi.runconfig file and observe the aml_config files created after exp.submit. Done means the requested configuration is loaded rather than local.runconfig and unrelated template files are not unexpectedly created.
