Big Switch: Uneccesary init method and server_timeout param

[Kevin Benton]

Both the Big Switch Plugin and ML2 driver allow a server_timeout param in the initialization methods that can never be set by a user so it doesn't serve a purpose [1][2]. With those removed, the entire __init__ method of the base class can be removed as well.

    Big Switch: Remove unnecessary initialization code

    Removes a server_timeout parameter that was never set by anything
    in the Big Switch plugin and the ML2 driver.

    Also eliminates an __init__ method that didn't do anything except
    incorrectly log an unset server pool warning before the inheriting
    class setup the server pool.

    Closes-Bug: #1331249
