Content Security Policy support for Google Tag Manager

[swetankrathi]

I am trying to setup Google Tag Manager(GTM) using this config

theme:
  name: readthedocs
  analytics:
    gtag: G-XXXXXXXXXX

However, this is working fine on local, there is Content Security Policy(CSP) issue with github pages as https://www.googletagmanager.com is not allowed in CSP.

Here is the screenshot

Can we add an option to config to allow https://www.googletagmanager.com in CSP? More on this can be found here.

Let's close this off in favor of #3630

Including GA should be supported as a template override, not a config option.
