Always pass NODE_OPTIONS with max-http-header-size (#5452)

* cli: set NODE_OPTIONS=--max-http-header-size=1024*1024 on spawn

* electron: remove redundant max-http-header-size

* server: add useCli option to make e2e tests go thru cli

* server: add test for XHR with body > 100kb via CLI

* clean up conditional

* cli: don't pass --max-http-header-size in dev w node < 11.10

* add original_node_options to restore o.g. user node_options

* force no color
