[Formrecognizer] Migrate recordings to asset repo

[samvaity]

This PR migrates the test recordings using test proxy for formrecognizer SDK to the assets repo.

Migrate recordings from language repositories to assets repo

Prerequisites:

• The script generate-assets-json.ps1 will execute the initial migration of your recordings from within a language repo to the assets repo as well as creating the assets.json file for those assets.

• Test-proxy needs to be on the machine and in the path. Instructions for that are here.

Running the script:

The script needs to be executed inside an sdk/ServiceDirectory/Library level directory.

C:/repo/sdk-for-java/sdk/formrecognizer/azure-ai-formrecognizer> ..\..\..\eng\common\testproxy\transition-scripts\generate-assets-json.ps1 -InitialPush

Examples of current assets.json locations:

• sdk/data/aztables/assets.json
• sdk/keyvault/azure-keyvault-keys/assets.json

After running a script, executing a git status from within the language repo, where the script was invoked from, will reflect two primary results:

• A new assets.json will be present in the directory from which they invoked the transition script.
• A bunch of deleted files from where their recordings were before they were pushed to the assets repo.

Running the script without the -InitialPush option will just create the assets.json with an empty tag. No data movement.

Using test proxy going forward:

C:\repo\azure-sdk-for-java.assets\tag-ref\java\sdk\storage\azure-storage-queue\src\test\resources\session-records\QueueServiceAsyncApiTests.listQueues[3].json
locally is where you should find your local copy of recordings.
