Add configurable timeout to netcat calls with 10s default (#78370)

Browse Source 
Add configurable timeout to netcat calls with 10s default

Without any timeout, netcat can get stuck forever (until Kubernetes
kills unhealthy Pod) when configured address and port combination is
wrong, or the connection gets stuck.
For example `nc -z bitnami.com 12345` doesn't seem to ever finish.

In the case when an attempt gets stuck, the timeout will allow further
attempts to be performed, instead of waiting until Pod is killed.
