Expression Language now supports padding functions:
- padLeft:
- attr:padLeft(Int n, Char c) will prepend to the `attr` attributes the `c` character until the size `n` is reached
- attr:padLeft(Int n) will prepend to the `attr` attributes the `'_'` character until the size `n` is reached
- padRight:
- attr:padRight(Int n, Char c) will append to the `attr` attributes the `c` character until the size `n` is reached
- attr:padRight(Int n) will append to the `attr` attributes the `'_'` character until the size `n` is reached
- In both cases, the padding function returns the `attr` `String` as is if its length is already equal of higher than the desired size `n`
- Returns null if `attr` does not exist or in case desiredLenght is higher than Integer.MAX_INT
Further test cases:
- Returns null if the input string is null
- Returns a string full of padding if the input string is empty
Supports PaddingString instead of PaddingCharacter

- Added nifi-parameter module
- Added Parameter to nifi-api
- Added ParameterContext and ParameterLookup
- Updated EL to support Parameters
- Updated backend so that any property can make use of Parameters

- Updated Templates to make use of Parameter Contexts
- Updated Versioned Flows to make use of Parameter Contexts
- Updated Stateless NiFi to support Parameters and take Parameters as part of the configuration, not Variables.
NIFI-6380: Addressed review feedback and fixed bugs; added additional unit and integration tests to verify
NIFI-6380: Added Description to Parameter Context
NIFI-6380: Fixed checkstyle violations
NIFI-6380: Fixed bug that caused updating a Parameter Context to fail if the name is provided and unchanged
NIFI-6380: If parameter is being deleted, don't worry about its sensitivity flag. This addresses a bug where the deletion of a Sensitive Parameter would require that the Parameter be submitted with a value of null and a sensitivity flag of true; else it would provide an error indicating that the parameter can't be changed from sensitive to non-sensitive. Now, the sensitivity flag is ignored.
NIFI-6380: Fixed bug around unsetting Process Group's Parameter Context
NIFI-6380: Moved lastRefreshed timestamp from ParameterContextDTO to ParameterContextsEntity and renamed to currentTime to match the pattern of ControllerServicesEntity rather than FlowHistory. Added parameterContextId to ProcessGroupFlowDTO
NIFI-6380: Added additional integration tests around escaped parameter references
NIFI-6380: Additional tests and bug fix for referencing EL from within another EL Expression
NIFI-6380: Created ParameterEntity to house a 'canWrite' flag for parameters and updated ParameterContext to use it. Updated ParameterContextUpdateRequestDTO to include a Set<AffectedComponentEntity> indicating the components that are affected by the update
NIFI-6380: Addressed review feedback
NIFI-6380: Addressed additional review feedback, mostly around code cleanup
NIFI-6380: Bug fix
NIFI-6380: Addressed more review feedback; fixed a couple of minor bugs encountered when testing
NIFI-6380: Bug fix around Parameter escaping for properties that support Expression Language. Fixed inconcsistency in Authorization hierarchy between /parameter-contexts/1234 and /parameter-contexts to ensure that the parent of /parameter-contexts is /controller, regardless of how we arrive at the /parameter-contexts resource
NIFI-6380: Fixed but around using ProcessContext#newPropertyValue(String) that previously resulted in causing the Parameters to be evaluated a second time, thereby ignoring escape characters. Updated Integration Test to verify behavior. Also fixed bug in LoadBalanceQueueIT as it was a one-liner and noticed it while running tests to verify other behavior
NIFI-6380: Ensure that if Processor or Controller Services references or de-references a Parameter that user making the change has READ policy on the Parameter Context
NIFI-6380: Verify permissions on Parameter Context when creating processor/controller service and when moving between groups, insantiating template, reverting/change flow version
NIFI-6380: Addressed problem that resulted from rebasing against master; fixed bug in showing the Affected Components for a particular Parameter Context Update
NIFI-6380: Fixed NPE that occurs when attempting to update controller-level Controller Service
NIFI-6380: Updated validation error text when referencing parameter from controller-level controller service or reporting task
NIFI-6380: Ensuring permissions for copy/paste when components reference parameters.
NIFI-6380: Do not require READ policy on Parameter Context in order to un-reference a parameter, only to reference one.
NIFI-6380: Restricted parameter names to match those in the Feature Proposal. Fixed bug that allowed copy & paste of a PG for which user does not have READ policy for a child/descendant PG's parameter context

- EvaluationContext gets passed through evalutors for each query
- evaluator tree is reused for multiple evaluation calls
- added extensive test cases for reusing prepared queries
- fixed tiny bug in DelineatedAttributeEvaluator
NIFI-6323 Changed URLs for splunk.artifactoryonline.com to use HTTPS (certificate validity warning in browsers, but command-line connection using openssl s_client is successful).
NIFI-6323 Changed URLs for XMLNS schema locations to use HTTPS (the XMLNS and schema identifier remain http:// because they are not designed to be resolvable).
NIFI-6323 Fixed Maven XML schema descriptor URLs.
This closes#3497
EL 'or' and 'and' functions can be called multiple times within the same context using the same evaluator instance.
That happens if their subject is derived from an IteratingEvaluator such as 'anyDelineatedValues'.
And if the right hand side expression for such 'or' and 'and' contains another IteratingEvaluator,
then it can be evaluated more than the number of its candidates, ultimately an ArrayOutOfBoundsException is thrown.
This commit makes Or/AndEvaluator caching its right hand side result to prevent that happens.
For 'or' and 'and' functions, the right hand side expression is independant from their subject boolean value.
It's enough evaluating right hand side once, because it returns the same result even with different subjects.

- Updated FlowFile Repo / Write Ahead Log so that any update that writes more than 1 MB of data is written to a file inside the FlowFile Repo rather than being buffered in memory
- Update SplitText so that it does not hold FlowFiles that are not the latest version in heap. Doing them from being garbage collected, so while the Process Session is holding the latest version of the FlowFile, SplitText is holding an older version, and this results in two copies of the same FlowFile object
