refactor: decrease compile time for golang plugins

Browse Source 
This change refactors the compiled golang plugins into 3 distinct binaries:

- commands: already existing
- subcommands/subcommands: entrypoint into all subcommands
- triggers: entrypoint into all triggers

It then further symlinks triggers and subcommands to the built binaries. This results in both a much faster build process as well as smaller package size.
