Add --bail cli flag, exit with non-zero status if scanning results in error, fixes: #370

[vidhill]

Feature request #370

When using the swagger-jsdoc cli in an npm script

If the scan fails the process currently exits with an exit code 0 which indicates success

When running on CICD for example,
I would like the job to fail so the process would need to exit with non-zero code

This PR adds a cli flag (--bail), when the flag is set exit with non-zero code if scanning fails

e.g.

npx swagger-jsdoc -d definition.js -o api-docs.json index.js --bail

If the scan fails, the script exits with code 1 otherwise it exits with 0 as normal
