Azure Blob Storage, Azure File Share and SharePoint Online Connector Apps

[IceOnly]

This PR contains three new connector apps, to connect Azure Blob Storage, Azure File Share and SharePoint Online with the New File System Module in the System App.

File System Module PR:
microsoft/BCApps#663

Here are some Screenshots:

Some general thoughts:
I think we need some kind of path serparated from the name added to the file account content.
It's often very important to know the path.

Additionally we might need some additional kind of top level selection before List Directories:
I'm thinking about a webservice for local file system access, there we should be able to select the Drive "C:" or "D:".
For Azure File Share we should be able to select the File Share on a top level before searching directories and files.

Further more if I take a look at the current sharepoint client. I have no idea how we should map this to the current provided
interface "File Connector".
https://github.com/microsoft/ALAppExtensions/blob/main/Modules/System/SharePoint/src/SharePointClient.Codeunit.al

Sometimes a path isn't enough and we might need more information to download a file.
Maybe this info could be added to the table 70005 "File Account Content" table and the interface "File Connector" could accept a "File Account Content" as parameter instead of a path....

Maybe someone else with more experience has some ideas how this access can be unified...

Why not listing C: and D: as directory on the top level?
The path is part of the Fiel Acount Content table. It is splitted in Parent Folder and Name.

However, I am not sure if the module should define the path separator. So all Services uses the same path structure and the implentation need to translate if needed.

Looks cool! I have a few small performance and security concerns, which I have addressed, and some minor other stuff, but nothing major. I'm excited for this.

Let me amplify this on Twitter/X to get your initial question answered: "before I go round the whole thing, I'm interested in whether there is any interest in the module at all". Let's see what people have to say! 😊

I support every effort to improve file handling.

Wonderful! Please merge this 👍🏻

Easily overlooked feature but a needed one. Huge development effort that should not be thrown away.
Perhaps I will find some time to invest in contribution from my side but cannot make promises at the moment.

[TheDoubleH]

Bravo! Love seeing more 'helper' features/functions that eventually will benefit all of us!

@IceOnly, this PR seems to have stagnated a little (which is perfectly fine). I was just wondering if you want to push this forward at some point, or if you've changed your mind / cannot find the time? There seems to be plenty of interest for this module in the community!

It is the time. I will try to find some free time to make the last changes.

This are my open points:

• I am struggling with the wist from pri-kise to split the Main Interface in logic interfaces like one for File, one for Directory and one for Account access. I like the Idea to implement one Interface and you are done.
• I will try to implement a realy simple pagination interface. The Most file services uses realy different methods for getting the next batch. So i will only alow the implemntation to result a pagination codeunit that can store the inforamtion it needs to get the next batch. How big a batch is can only be defined by the implementation.

[JesperSchulz]

Feel free to do it at your own pace. I didn't mean to stress you. I was just curious if you still intend to continue work. If you do, we'll just leave this PR open. No problem whatsoever.

@JesperSchulz I need an three Object Ranges for this Apps. Which one can I used? The highest object type count is three objects.
I'm also not sure which namespace to use. Or simply use none, as in the email apps?

@IceOnly could you maybe add the 2nd Authentication Type for SharePoint that was added recently .
This would require a few new Fields: Enum SharePointAuthType , a "Certificate Password Key" and a Certificate Password (Blob)

See: microsoft/BCApps#705

TempBlob2 is unused.

@IceOnly regarding your issue with the empty stream.
Take a look at the following issue: Stream

Why aren't you directly using the parameter Stream in the procedure DownloadFileContentByServerRelativeUrl?
