Update to edc version 0.8.X

[tunacicek]

WHAT

We are using this template repository to include our own edc extension and build a custom image.
Wenn updating to tx version 0.8.0-rc4 and edc version 0.10.XX, it is possible to build the custom image successfully.
But it is not possible to run this image.
I got a error message:
'/__cacert_entrypoint.sh: exec: line 104: illegal option --'

WHY

HOW

Possible solution:
In dockerfile, use ENTRYPOINT instead of CMD
