Looking up a symbol from plugin java code

[Vincent Latombe]

Hello,

We're reviewing usage of icons across our plugin codebase and adapting to the new symbols.

Context:

* https://github.com/jenkinsci/jenkins/pull/6186

* https://github.com/jenkinsci/jenkins/pull/6532

We have a use case where an icon is returned through a FormValidation object. FormValidation#respond currently takes arbitrary html as input so to replace an arbitrary icon with a symbol, we'd need access to IconSet#getSymbol which is currently @Restricted(NoExternalUse.class).

Would it make sense to relax it or should another way be explored for this use case?

Cheers,

Vincent
