This is the first in a series of commits to allow for the use of gem5 as a target in devlib.
The interaction with the gem5 simulation is done by the Gem5Connection, a type of TelnetConnection.
There are two types of Gem5Connections (Linux and Android) as they differ slightly in the implementation
of some methods. Other types of connections have only been changed to make them uniform (e.g. arguments for init method)

Perviously, a parameter passed into SshConnection controlled whether the
connection was established over SSH or Telnet. Now, there is a separate
class for Telnet connections.
Now that connection classes can be passed as arguments on Target
instatiation, they are part of the user-facing API and are marked as
such by exporting them in the main __init__.py
