Allow overriding of plugin paths

[srikanth-viswanathan]

Currently the plugin paths are hardcoded in the python code. The deployment location of custom plugins might be different than the deployment location of simoorg, so it would be nice to allow the plugin paths to be overriden. My suggested way of doing this would be to add an optional parameter in the fate book to control the search location for plugins:

plugin_base_path: /my/custom/plugin/deployment/location
topology_plugin: MyTopologyPlugin

Currently, I have it working by starting simoorg inside my custom startup script where I override the relevant atropos.*_PLUGIN_PATH global variable, but I'd rather not do this if simoorg supported custom plugin paths out of the box.

Sounds reasonable to do.

Good to work on it. Feel free to submit a PR when done :)

Hey @srikanth-viswanathan, Just wanted to see if you are actively working on the current issues that you raised with Simoorg. they seem to be really nice suggestions. Let me know :)

Haven't had time to work on these yet. I hope to do a couple next week.
