[MUSIC][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. Also, decrease number of replicas from 3 to 1 Issue-ID: OOM-2742 Signed-off-by: Sylvain Desbureaux <sylvain.desbureaux@orange.com> Change-Id: Ideb0ede251332e182b975ff18ca5a75bcbff2351
