running remotetests takes a looong time

[mukundha]

The deploy proxy in remotetests steps takes about 50-60 seconds and sometimes timing out

Proposal 1 - use a simpler proxy with just express - there is no need to include node_modules if its just express, so the bundle size could become significantly smaller and deployment faster 2 - for non-nodejs test, we could use a simpler proxy that does not have nodejs resources - might fasten the tests
