Use tsconfig.json compilerOptions

[vellengs]

support for project's tsconfig.json

Good start. I think this needs a couple things before a merge though:

• (Optional) Add a configuration option tsConfigFile to override the default location of the tsconfig.json file
• Handle the case where require throws an error because tsconfig.json doesn't exists where you're looking for it and fallback to using empty config
• Handle the case where tsconfig.compilerOptions is undefined and fallback to using empty config
• Fix linting error ERROR: src/metadata/metadataGenerator.ts[14, 68]: trailing whitespace

@ngraef It's good strict for that; I have a suggestion. why not move to configurable swagger.config then user make the decision.
