Bug Description

Ensure "keepalived" is correctly disabled, that means the process does not exist. Currently the process is terminated sending a SIGTERM signal [1]. If that fails, for any reason, the "keepalived" process will continue running. For example in [2][3]: the SIGTERM signal is sent but the process is still running ("psutil.Process(pid)" is able to retrieve the process information).
