Release notes for Optimizely CMS and Customized Commerce updates

Updated package dependency range to Episerver.Find 15.

Fixed EPiServer.Commerce.FindSearchProvider to support Find 15.

CatalogContentEventListener.IndexContentIfNeeded can get into an infinite loop when executing multiple threads. You should use ConcurrentDictionary instead of using standard dictionaries. 

Fixed an issue where a second search would not produce a result. If you cleared the content index and then started Search & Navigation Content Indexing Job manually, the first search in the Search box of the catalog tree performs correctly, but the next one did not.

Updated the Newtonsoft.Json dependency version from 12 to 13.

(Episerver.Find already supported Newtonsoft.Json 13)

Fixed issue with ability to set FindCommerce event indexing to allow for temporarily disabling of event indexing. 

CatalogContentClientConventions.AllowIndexingCatalogContent should be possible to set dynamically. Furthermore, IsListeningToPriceEvents, IsListeningToInventoryEvents and IsListeningToLowLevelApiEvents should be introduced, and also possible to set dynamically to allow fine grain control of the indexing.

Fix to improve performance of catalog intensive operations such as import, when loading language versions.

Steps to reproduce

1) Deploy a Commerce site using FindSearchProvider to Azure.
2) Make sure everything works as expected, i.e: you can search the catalog in Catalog Entry Search of Commerce Manager, the FindSearchProvider gets values from app settings of web app.
3) Update serviceUrl and defaultIndex in Mediachase.Search.config to invalid values, i.e:
serviceUrl="https://es-eu-dev-api01.episerver.net/BG2y7vnuQICkEqmEOVHAK7SVcuNX4xH4" defaultIndex="dinhnguyen_20190830".
4) Re-deploy the Commerce site.
5) Make sure app settings still have serviceUrl and defaultIndex values. And these values are valid.
6) Navigate to Commerce Manager -> Catalog Management -> Catalog Entry Search.

Expected
No errors, be able to search catalog.

Actual
"401 Unauthorized" error displays. Because the FindSearchProvider doesn't get values from app settings, it still gets value from Mediachase.Search.config file. If you restart the web app, then rebuild the Index in the Administration UI, it works as expected.
