[nan-903] add optional integration-id

[khaliqgant]

Describe your changes

If a user has repeated sync names then we (nango) might not know how to resolve the script to run in a dry run

integrations:
  provider-1:
   syncs:
     foo:
  provider-2:
    syncs:
      foo:

This allows a user to pass in an optional flag of integration-id to identify provider-1 or provider-2

nango dryrun foo unique-connection --integration-id provider-2

NAN-903 dryrun isn't picking up the correct provider config key when using nested directories

sidenote: I would love if all dryRun params could be named including connection and sync name because I always forgot in which order there are supposed to be passed.

Yeah same. That is a big change though as dry run is a very often used command cc/ @bastienbeurier
