Add --disable-host-check to allow external access

[wooldridge]

When installing and running QuickStart on an ML VM, I couldn't access that QuickStart app from my remote machine, i.e. via:

http://engrlab-129-036.engrlab.marklogic.com:4200/

Adding --disable-host-check to the "ng serve" command fixed this:

ng serve -pc proxy.config.json --host 0.0.0.0 --disable-host-check

This is discussed here:

There are reported security implications:

Note that I was not able to solve the issue by adding a --public option (with marklogic.com or *.marklogic.com) instead, which is mentioned in the above article.

Can one of the admins verify this patch?

Since this isn't a production supported feature yet, I'm going to allow this through.

We'll need to discuss having this only happen during development environments in the future if this extends to production use.
