NIFI-3404: Improved UX of LookupAttributes.
- Added dependency notice.
- Added EL evaluation at SimpleKeyValueLookupService.
- Updated documentation.
- Updated CommonsConfigurationLookupService to throw LookupFailureException if
it fails to get configuration so that error messages can be displayed at each
processor bulletin.
- Added calling getConfiguration at OnEnabled of
CommonsConfigurationLookupService, so that the service will stay in Enabling
state if there is any issue.

> Add lookup processor for enrichments/joins to reference data

> Key: NIFI-3404
> URL: https://issues.apache.org/jira/browse/NIFI-3404
> Project: Apache NiFi
> Issue Type: Improvement
> Reporter: Joey Frazee
> Assignee: Joey Frazee
>
> NiFi doesn't currently have an easy, concise way of doing enrichment, joining
> against reference data sets or performing attribute lookups against external
> data sources.
> Since enrichments and joins are basic streaming use cases, and since
> attributes and EL are often used to parameterize processor properties, there
> is a need for an easy way to do enrichments, joins and lookups without having
> to write code or create a lengthy data flow.
> There's been some discussion of this on the mailing list [1] and I've started
> work on a LookupAttribute [2] processor that delegates the work to controller
> services.
