Azure Functions integration with Cognitive Services

This function scans for a blob-storage container (specified by env variable Container) for images and send them over to Cognitive Services for Read-In.

The result is filtered by RegExp provided in env variable RegExpMatcher

The filtered result is loaded in CosmosDB database provided in env variable Database and Collection Collection

The cognitive services instance is configured to env variables CsUrl and CsAccessKey

There is PDF splitting Function in action as well configured with the input container PdfSplitter and output container ``PdfSplitteOutput```. These can be same as well.

The plitter can share container with form-recognizer. A filtering variable was added to support that: FRFilter. Even if the container are not shared, the filter should be at least '.pdf'.

Container names can include directory names
