> Issue Type: Bug

> While using kubernetes-discovery with cellar I came across this issue . The
> default etc/hazelcast.xml has tcp-ip disabled and multicast enabled.
> In this scenario , when kubernetes-discovery runs and discovers members ,
> adding them to tcpConfig throws an NPE
> {noformat}
> java.lang.NullPointerException: null

> I updated the etc/hazelcast.xml to enable tcp-ip and expected this error to
> go away but I still continued to get the above NPE since TcpIpConfig wasnt
> updated .
> I had to manually restart hazelcast bundle to fix the above error post the
> hazelcast.xml changes.
> Can we look at triggering the update of TcpIpConfig in case of changes and
> also if possible update this config automatically when cellar-kubernetes
> feature is installed to avoid having to update the etc/hazelcast.xml manually
