[COMMON][CASSANDRA] Use Startup probes
Instead of long initial delay on readiness and liveness probes, use startup probes and be more aggressive on readiness and liveness. Issue-ID: OOM-2741 Signed-off-by: Sylvain Desbureaux <sylvain.desbureaux@orange.com> Change-Id: If60f345fd1e11fd1419cee58efb7d53e56dc5c79
