Moved web application deployment locations.

Currently web applications are deployed into Host's appBase (i.e.
<instance>/webapps). To allow better control of individual
subsystem deployments, the web applications have to be moved out
of the appBase so that the autoDeploy can work properly later.
This patch moves the common web applications to <instance>/
common/webapps and subsystem web applications to <instance>/
<subsystem>/webapps. An upgrade script has been added to update
existing deployments.
