Targets command fails when using integration other than github-enterprise

[ebickle]

Running the command python cli.py --github-token <token here> --conf snyk-sync.yaml --snyk-orgs-file snyk-orgs.yaml --cache-dir cache targets results in an unhandled exception:

KeyError: 'github-enterprise'

The snyk-sync.yaml file has the following:

default:
   orgName: orgNameHere
   integrationName: github

Line 436 and 439 of cli.py appears to have a bug - the YAML key github-enterprise is hardcoded. For users who are using regular GitHub and not GitHub Enterprise, these lines will always crash with an error. They should be updated to select the proper integration from configuration rather than being hard-coded.
