shellsink-client does not work with SNI SSL backend

[Jack Zielke]

When attempting to connect to an SSL server that uses SNI (like cloudflare) shellsink-client puts the following error in the syslog.

shellsink-client: ERROR: Shellsink unable to contact server at https://domain.com/addCommand. Reason: [Errno 1] _ssl.c:510: error:14077438:SSL routines:SSL23_GET_SERVER_HELLO:tlsv1 alert internal error

• pyOpenSSL (tested with 0.13)
• ndg-httpsclient (tested with 0.3.2)
• pyasn1 (tested with 0.1.6)

sudo apt-get install build-essential python-pip python-dev libffi-dev libssl-dev
sudo pip install --upgrade requests pyopenssl ndg-httpsclient pyasn1

Fixes #1, replace urllib2 with requests. This raises the requirements to python 2.7

Fixing this raised execution time from 0.2 sec to 0.6 sec.

More like 1.5 - 2 seconds. Fixed by moving import requests after os.fork().
