Directory mounting frenzy

[plasorak]

With this PR, nanorc now mounts, in the application pod:

• DBT_INSTALL_DIR for using binaries/libraries (the correct PATH/LD_LIBRARY_PATH/CET_PLUGIN_PATH env variables are also set),
• the configuration directory,
• PWD/logs directory (or the one in /logs for nano04rc) to a directory /logs where all the app logs are redirected,
• PWD/trace directory where the trace buffers are.

Going to close this, since we decided this isn't the correct way to do things.
