set lib/otb/applications default for OTB_APPLICATION_PATH
OTB_APPLICATION_PATH is to set location of where apps are installed. This is helpful for external projects. But do we really need this stuff on default install?
There is otbcli (.sh and .bat) which will set a path if not exists. could we add /lib/otb/applications (or INSTALL_APP_DIR). environment variables can be used to configure additional apps if any?
making this change in AppEngine is necessary because it will benefit otbcli, otbgui, mapla, python, QGIS.
bonus: people cannot override official otb apps such as a malware named /tmp/otbapp_ReadImageInfo.so
