helm: Add tetragon.livenessProbe value

[ upstream commit 1871fe8 ] Add tetragon.livenessProbe Helm value that overrides the default liveness probe for the tetragon container. For example, to use grpc probe, you can specify tetragon.livenessProbe Helm value like this: tetragon: livenessProbe: grpc: port: 54321 Signed-off-by: Michi Mutsuzaki <michi@isovalent.com>
