Log request and response debug log together for easy debugging

[jeevatkm]

The goal is to improve Resty debug log readability. Log request and response debug log together for easy debugging instead of separately. Importantly its highly helpful in multi-goroutine usage.

Current:

---------------------- REQUEST LOG -----------------------
POST  /login  HTTP/1.1
HOST   : 127.0.0.1:52620
HEADERS:
             Content-Type: application/json; charset=utf-8
               User-Agent: go-resty/1.11.0 (https://github.com/go-resty/resty)
BODY   :
{
   "password": "testpass",
   "username": "testuser"
}
----------------------------------------------------------
RESTY 2019/01/10 00:55:44
---------------------- RESPONSE LOG -----------------------
STATUS 		: 200 OK
RECEIVED AT	: 2019-01-10T00:55:44.218642-08:00
RESPONSE TIME	: 1.042026ms
HEADERS:
           Content-Length: 51
             Content-Type: application/json; charset=utf-8
                     Date: Thu, 10 Jan 2019 08:55:44 GMT
BODY   :
{ "id": "success", "message": "login successful", }
----------------------------------------------------------

Sometimes curl-style logs are useful, especially if you need to manually resend a request, or send it to someone else to reproduce the scene
