Add a history command and shared history accessible across machines

[pulkitsinghal]

1. Depending on the developer (me), the commands can get kind of long~ish and the only thing that autocompletes is the program name and not the commands. So I hear feedback about how that's a pain. So a shared history across machines would be quite a sweet feature. It would let users leverage copy/paste from within the terminal like:

   $ vend-tools history
   1. vend-tools my-custome-command-name --myOptionA value --myOptionB value
   2. vend-tools my-custome-command-name --myOptionA value --myOptionB value
   ...
   9. vend-tools my-custome-command-name --myOptionA value --myOptionB value
   

2. Also if users set the defaultOutputDirectory in settings.json then the history.json file can be accessible across machines.
