Make response security headers built-in

[ceilfors]

Is your feature request related to a problem? Please describe.
It's common to configure security headers in API endpoints. See: https://github.com/helmetjs/helmet. We needed to configure this manually in most of our projects after we got a penetration testing report.

The one that always come back to us is:
'Strict-Transport-Security': 'max-age=.....; includeSubdomains;'

Describe the solution you'd like
Something like this:

const adapterApi = require("@laconia/adapter-api");

const apigateway = adapterApi.apigateway({
  responseSecurityHeaders: true // Should `true` be default? Is this a breaking change?
})

exports.handler = laconia(apigateway(app)).register(instances);

In our first iteration, we can support only all the sensible defaults, and support customisation in the next iteration like:

const apigateway = adapterApi.apigateway({
  responseSecurityHeaders: {
    // options
  }
})
