Start container with different command AND different user

[svettwer]

As a sakuli user, I want to start the container with a different user -u 1001:1001 and with a different command e.g. bash, so be able to work on mounted volumes with the correct user ID in bash.

Acceptance criteria:

• it is possible to start the container with -u and altered command e.g. bash

Test case to reproduce:

# start another command than sakuli with another user
docker run \
    --rm \
    -e SAKULI_LICENSE_KEY=${SAKULI_LICENSE_KEY} \
    --shm-size=2G \
    -u 45678:12345 \
    taconsol/sakuli:${1:-latest} \
    "echo success!"

currently results in:

ln: failed to create symbolic link '/testsuite_execution/node_modules/node_modules': Permission denied
