feat: silence or minimize output of jina ping command

[girishc13]

Describe the feature

The jina ping command is also used for the startup, readinesss and/or liveness probe. The command currently by default prints the jina logo and the arguments of the command which pollutes the kubernetes events logger and the pod events.
