Allow selecting the Node.js binary OSD uses (#3508)
New reusable use_node scripts take care of selecting the correct Node.js binary based OSD_NODE_HOME, OSD_HOME, and whatever is in the PATH. It also takes care of finding the binary on FreeBSD. * The startup scripts check `OSD_NODE_HOME` and `NODE_HOME` before falling back to use the bundled or system-wide Node.js binary. * Update `package.json` to replace `node` with `use_node`. * Update file templates and shell scripts to internally use `use_node`. * Update the build scripts to copy `use_node` into releases * Make tests that execute node internally, honor the binary being used.
