handling of timeout for test containers fails when timeout is reached

[greygoo]

At

catapult/modules/tests/kubecf-test.sh

Line 44 in 543bc71

if [[ "${timeout}" == 0 ]]; then return 1; fi

we use return outside a function, which results in the error

./kubecf-test.sh: line 53: return: can only `return' from a function or sourced script when the timeout is reached for whatever reason.

This is also present in several other lines in the script that als use return outside a function

This may have been fixed with the refactor of #151
