fix: Clean up service containers on DLE failure #213

Description

Sometimes DLE during emergency exit does not clean-up service containers. It could lead to data corruption (for details see #213 (closed))

To fix this issue we have to handle carefully error cases during DLE initialisation

• cancel context to stop changes from go-routines
• stop and remove all running service containers
