NIFI-2714 Added regex support to ConsumeKafka_0_10
Enabled the ability to specify topics as a regular expression as natively
supported in the Kafka client. The current ConsumeKafka* modules only support
the topic name as a single string or list of strings. The regex (Pattern
object) format is much more flexible.
This is implemented with a new PropertyDescriptor to differentiate between
string name(s) and patterns, defaulting to the existing string(s). It might be
possible to automatically identify strings or patterns, but since some strings
are also valid regex patterns with slightly different meanings it seems safer
to set a property -- as @joewitt commented on this ticket in Aug. 2016.
Updated Kafka client from 0.10.0.1 to 0.10.1.1

> Whitelist and Blacklist for Topics in ConsumeKafka

> Project: Apache NiFi
> Issue Type: Improvement
> Reporter: Sam Hjelmfelt
> Assignee: Joseph Witt
> Priority: Minor
>
> The Kafka API has methods to receive a pattern when selecting the topics to
> consume. Allowing the user to provide a whitelist or blacklist regular
> expression would improve the flexibility of this processor. This is similar
> functionality to what is supported by the Kafka mirrormaker.
