Description

Since NiFi 1.3.0 and NIFI-391, we can add a

@DeprecationNotice

annotation to components that we want to deprecate.

As of now, this deprecation notice is only reflected in the Usage documentation. But it can be completely missed by users and it can also be completely unnoticed on existing workflows.

I suggest the two following improvements:

• In the component listing, strikethrough the line displaying the component and prefix the description with "DEPRECATED (see usage for more information)".
• Just like we have a specific icon for processors running on the primary node only, it could be a good idea to have an icon with something like an exclamation mark instead of the "P".

Thoughts?
