(cherry picked from commit a1f8e70)

* NIFI-6510 Updated objects and interfaces to reflect 4 prediction metrics

(cherry picked from commit 050e0fc)

(cherry picked from commit 9fd365f)

(cherry picked from commit 14854ff)

DFA-9 - reduced snapshot interval to 1 minute

(cherry picked from commit 36abb0a)

* NIFI-6510 Split StatusAnalytics interface into Engine and per-Connection versions

* NIFI-6510 Remove redundant connection prediction interfaces as we can just use ConnectionStatusAnalytics directly

* NIFI-6510 Revert "DFA-9 Remove redundant connection prediction interfaces as we can just use ConnectionStatusAnalytics directly"

This reverts commit 5b9fead1471059098c0e98343fb337070f1c75c1.

* NIFI-6510 Added prediction fields for use by UI, still need to be populated

* NIFI-6510 Analytics Framework Introduction (#10)

* DFA-9 - Initial refactor for Status Analytics - created additional interfaces for models, refactored callers to use StatusAnalytics objects with connection context. Implemented SimpleRegression model.

DFA-9 - added logging

* DFA-9 - relocated query window to CSA from model, adding the prediction percentages and time interval

* DFA-9 - checkstyle fixes

* NIFI-6510 Add prediction percent values and predicted interval seconds

(cherry picked from commit e60015d)

* NIFI-6510 Changes to inject flowManager instead of flow controller, also changes to properly reflect when predictions can be made vs not.

(cherry picked from commit 6fae058)

* NIFI-6510 Added tests for engine

(cherry picked from commit 6d7a13b)

* NIFI-6150 Added tests for connection status analytics class, corrected variable names

(cherry picked from commit 58c7c81)

* NIFI-6150 Make checkstyle happy

(cherry picked from commit b6e35ac)

* NIFI-6150 Fixed NaN check and refactored time prediction. Switched to use non caching engine for testing

* NIFI-6510 Fixed checkstyle issue in TestConnectionStatusAnalytics

* NIFI-6510 Adjusted interval and incorporated R-squared check

Updates to support multiple variables for features, clearing cached regression model based on r-squared values

Added ordinary least squares model, which truly uses multivariable regression. Refactor of interfaces to include more general interface for variate models (that include scoring support).

Ratcheck fixes

Added test for SimpleRegression. Minor fix for OLS model

fixed test errors

fixed checkstyle errors

(cherry picked from commit fab411b)

* NIFI-6510 Added property to nifi.properties - Prediction Interval for connection status analytics (#11)

* NIFI-6566 - Refactor to decouple model instance from status analytics object. Also allow configurable model from nifi.properties

NIFI-6566 - changes to allow scoring configurations for model in nifi.properties

NIFI-6566 - added default implementation value to NiFiProperties

NIFI-6566 - correction to default variable name in NiFiProperties, removed unnecessary init method from ConnectionStatusAnalytics

Signed-off-by: Matthew Burgess <ma...@apache.org>

This closes #3663

* NIFI-6585 - Refactored tests to use mocked models and extract functions.  Added check in ConnectionStatusAnalytics to confirm expected model by type

* NIFI-6586 - documentation and comments

This closes NIFI-6586

* Add back pressure prediction ticks.
* add moment.js to format predicted time to back pressure
* tweak summary table headings to match data displayed. re-order connection summary columns

> In version 1.9.1, we made a fix for NIFI-6110 that prevented a Content Claim's count from being decremented if the FlowFile Repository fails to update. This was done to avoid a potential data loss bug. However, it had an adverse effect of causing Content Claims to never be cleaned up in some cases, which can lead to the Content Repository filling up and running out of disk space.
