Our policy so far has been that passwords do not support expression
language, for a couple reasons:
1. How to evaluate if a password `abc${def}` should be interpreted as `abc`
+ *the value of(`def`)* or the literal string `abc${def}`
1. The variable registry is not designed to store sensitive values
securely, so if a password is stored here, it can be accessed by an
unauthorized user
> Support variables for the properties of HTTP processors

> Project: Apache NiFi
> Issue Type: Improvement
> Components: Extensions, Variable Registry
> Affects Versions: 1.7.1
> Reporter: Kemix Koo
> Priority: Minor
>
> When set some group (global) variables, some properties of HTTP processors
> don't support the expressions. for example, USER and PASS, if don't set the
> global variables, must change for each processors one by one. it's so
> troublesomely.
