Introduce ConsoleHandler class under obmc_console

Added new ConsoleHandler class to prepare for the multiple consoles
support. All global fields are moved to the ConsoleHandler class and a
new global map added to remember the ConsoleHandler for each console
path. There is single ConsoleHandler per connection so we don't need
session map per route. There is a limit added for max number of
connection allowed to avoid any service attacks.

Testing:
    - Make sure that single console works fine and data is seen on the
      console.
    - Make sure that multiple consoles of type host console are created
      and data is seen on all consoles. Also using traces made sure
      that new handlers are destroyed.

Traces: Traces shows that multiple consoles active and later destroyed.
