[🚀 Feature]: Support custom node types besides chrome/firefox/edge in helm chart

[andrii-rymar]

Feature and motivation

Currently Selenium Grid deployed with helm chart only supports 3 main web browsers to run the tests against. It would be great to have a custom node besides chromeNode/firefoxNode/edgeNode to run mobile tests or the tests against another browser supported by Selenium.
Let's say I want to run the mobile tests against Android emulator and I have an image with the node (with relay configured), appium and the emulator itself. It would be nice to have a separate customNode where I can specify this image and something like browserName: android to spin off these nodes when this type is requested by the tests.
