Description
In order to have inline scripts and use a strict CSP, it's important to provide a nonce.
Spring Security's ContentSecurityPolicyHeaderWriter could generate a nonce if a {nonce} placeholder is in the policy directive configuration.
Then, it could be made available as a request attribute for use in views.
