Builder pod that hit timeout is not terminated

[christophd]

This is on Camel K 2.0

Since 2.0 the default build strategy is pod where each build is run via a builder pod. In case this build hits a timetout the Camel K operator tries to send a SIGTERM signal to the builder pod in order to terminate the build. Since 2.0 this mechanism is not working anymore (see error message below) and the pod and its build keeps running forever and all other builds get queued.

I think this problem is because of the kill command is not available in the builder Pod which now is created from Mandrel:

OCI runtime exec failed: exec failed: unable to start container process: exec: "kill": executable file not found in $PATH: unknown
