Add new interfaces used to abstract the main client class and contexts.

Browse Source 
Now developers can pass a client object or an executable context (see
Predis\Transaction\MultiExecContext or Predis\Pipeline\PipelineContext)
interchangeably as parameters to their methods using the new interface
Predis\BasicCliantInterface.

These new interfaces will also allow us to easily create new client
classes aside from the standard Predis\Client one.
