Register instance dependency

[hugosenari]

Is your feature request related to a problem? Please describe.

When I need to register a instance dependency, the current Laconia API is asking me to write a function, which lead to a verbose code and more code to test since coverage warn that I need test for required function.

exports.handler = laconia(kinesis(app))
  .register('logger', () => console.log);

Describe the solution you'd like [optional]

exports.handler = laconia(kinesis(app))
  .register({ logger: console.log });
