ansible kernel for jupyter

Tested under max osx 10.12 with ansible 2.3.X.

1. read hosts file from '/usr/local/etc/ansible/hosts'

   [tf]
   192.168.X.XXX ansible_python_interpreter="/usr/bin/env python3" ansible_ssh_user=remote_user_name ansible_become_pass=remote_user_password
   
   [local]
   localhost              ansible_connection=local
   

   tf and local group in hosts file, and input follow to show 'hello world' on to machine.

   hosts: tf, local
   tasks:
     - debug: msg="hello world"
   

2. human readable output

   TASK [localhost: TASK: Gathering Facts] 
   
   
   TASK [192.168.10.238: TASK: Gathering Facts] 
   
   
   TASK [192.168.10.238: TASK: debug] 
   hello world
   
   TASK [localhost: TASK: debug] 
   hello world
   
   ok
   

3. default hosts is localhost

   - debug: msg="hello world"
   - shell: ls -l
   

   output:

   TASK [localhost: TASK: Gathering Facts] 
   
   
   TASK [localhost: TASK: debug] 
   hello world
   
   TASK [localhost: TASK: command] 
   stdout:
   total 24
   drwxr-xr-x  4 mind  staff   136 Aug 11 18:01 2017
   -rw-r--r--  1 mind  staff   830 Aug 11 23:48 Untitled.ipynb
   -rw-r--r--  1 mind  staff  1090 Aug 14 16:32 Untitled1.ipynb
   stderr:
   
   
   ok
   

4. set gather_facts to false could skip 'Gathering Facts'

   hosts: tf
   gather_facts: no
   tasks:
       - debug: msg="hello world"
   

   output:

   TASK [192.168.10.238: TASK: debug] 
   hello world
   
   ok
   

5. use hosts set global default hosts

   # hosts=local, tf
   

$ pip install -e .
$ python -m ansible_kernel.install --sys-prefix
