[copyrighthero]

Describe the bug When deploying the function through the VSCode plugin, the remote environment variables are cleared and overwritten.

To Reproduce Steps to reproduce the behavior:

1. Click Deploy button on the VSCode plugin for the functions;
2. Go to your console, check the corresponding functions' settings;
3. See that previous environment variables were replaced by the following:

   {"LD_LIBRARY_PATH":"/code/.fun/root/usr/local/lib:/code/.fun/root/usr/lib:/code/.fun/root/usr/lib/x86_64-linux-gnu:/code/.fun/root/usr/lib64:/code/.fun/root/lib:/code/.fun/root/lib/x86_64-linux-gnu:/code/.fun/root/python/lib/python2.7/site-packages:/code/.fun/root/python/lib/python3.6/site-packages:/code:/code/lib:/usr/local/lib","NODE_PATH":"/code/node_modules:/usr/local/lib/node_modules","PATH":"/code/.fun/root/usr/local/bin:/code/.fun/root/usr/local/sbin:/code/.fun/root/usr/bin:/code/.fun/root/usr/sbin:/code/.fun/root/sbin:/code/.fun/root/bin:/code:/code/node_modules/.bin:/code/.fun/python/bin:/code/.fun/node_modules/.bin:/usr/local/bin:/usr/local/sbin:/usr/bin:/usr/sbin:/sbin:/bin","PYTHONUSERBASE":"/code/.fun/python"}
   

Expected behavior The previously set env vars should persist, these run-time related env vars should not have replaced and cleared previous ones.
