Parse Server option `masterKeyIps` vulnerability to IP spoofing

Description

Parse Server uses the request header x-forwarded-for to determine the client IP address. If Parse Server doesn’t run behind a proxy server, then a client can set this header and Parse Server will trust the value of the header. The incorrect client IP address will be used by various features in Parse Server.
