Requires restart of any dev shell sessions that may have KARAF_VERSION=3.0.2 already set.

Change-Id: Iba234b3cd5af89de6dd249c97cac97525364cc34
but with several differences:
* Default ONOS_ROOT value is $HOME/onos instead of $HOME/onos-next
* Convenience utility functions and aliases are not included
* $MAVEN/bin is not included in the executable path
* The 'cell' funcion from BASH is renamed to 'onos-setup-cell'
Also, 'onos-setup-cell' always requires an argument: the cell name
Displaying the current cell setup can be done by the
'onos-show-cell' script
