docs: Returns an object where the key is a header name and value is the header value.
  
  @param {Object=} options
  @param {Boolean} options.ignoreCase When set to "true", will ensure that all the header keys are lower case.
  @param {Boolean} options.enabled Only get the enabled headers
  @param {Boolean} options.multiValue When set to "true", duplicate header values will be stored in an array
  @param {Boolean} options.sanitizeKeys When set to "true", headers with falsy keys are removed
  @returns {Object}
  @note If multiple headers are present in the same collection with same name, but different case
  (E.g "x-forward-port" and "X-Forward-Port", and `options.ignoreCase` is set to true,
  the values will be stored in an array.
