Add option to deploy che component (che-dashboard, che-server, che-gateway, etc.) on specific nodes

[huonguyenlt]

Is your enhancement related to a problem? Please describe

I am deploying che on EKS. I want to deploy all the che components to the same node or node groups. However, it looks like there is no option to do that.
I install che using che operator. I can add the node selector to the che-operator deployment to install it on the specific node. But when che operator starts to deploy other che components (che-dashboard, che-server, che-gateway, etc.), all the components go to different nodes. Please help.

Describe the solution you'd like

1. If you already had the solution for it, please educate me. Or
2. add nodeselector option for each che component

Describe alternatives you've considered
