Feature request: support expressions starting with the hash-tag character

[JanSzkandera]

Is your feature request related to a problem? Please describe.

Currently, only the dollar sign JUEL expressions are supported by the converter, if useDelegateExpressionAsJobType is set to true.

Also the strings starting with a hash-tag are valid JUEL expressions.

Describe the solution you'd like

Support hash tag in the AbstractDelegateImplementationVisitor#L15.

The pattern should be like this

public static final Pattern DELEGATE_NAME_EXTRACT = Pattern.compile("[$#]\\{(.*)\\}");

Describe alternatives you've considered

• Maybe pass the pattern as a configuration property?
• Implement my own visitor instead.

Additional context

None.
