stack 1daded7951 HPE 3PAR: Reuse existing session

The 3PAR driver creates new SSH connection to the backend for each
operation (eg. create/delete volume).

There is a limit on maximum number of SSH connections from 3PAR
backend i.e 24 connections.

The problem is that when multiple concurrent operations are
performed, this limit gets reached & further operations get
errored out.

This patch performs two things:
[a] Instead of creating new session for each operation, an attempt is
made to reuse existing session for as most operations.
[b] Since WSAPI of 3PAR has evolved, wsapi (http/https) requests are
used; thus SSH connections are no longer required.
