feat(plugin): add simple plugin manager for release

[pfongkye]

• Adding a simple release plugin manager to allow for custom release managers to be added.
• Add your custom release manager to plugins/release folder at build time (if you add the plugin after the app starts, it won't be loaded dynamically).

TODO:

• extract types in its own npm package for implementing custom release manager.
• Add documentation on how to add custom release manager.
• Make release tag managers available as plugins also.
