Release notes for Optimizely updates

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.

Resolving startup errors of type ReflectionTypeLoadException should be easier to diagnose if the nested LoaderExceptions were exposed. This is even suggested by the default exception message:

"Unable to load one or more of the requested types. Retrieve the LoaderExceptions property for more information"

FindSearchProvider needs ServiceUrl and defaultIndex to be configured. However that is set by managed services for DXC sites, and they don't want to send out that information to customers. FindSearchProvider should fall back to appSettings if those values are not configured.
