Subject: [PATCH] [helm] Use grpc-based liveness probe

[upstream commit 2252857c7020fb4f155d556df1a759f807ca4d6b]

The previous commit introduced a gRPC server that can be used for
the liveness probe. This patch changes helm to make that default instead
of the tetra status based liveness probe.

The user can still use the tetra status based liveness probe by
defining a values file similar to:
tetragon:
  livenessProbe:
     timeoutSeconds: 60
     exec:
       command:
       - tetra
       - status
       - --server-address
       - "54321"
       - --retries
       - "5"
