[Netskope] Add system tests for multiple deployers

[moxarth-rathod]

The Netskope integration now includes three new data streams:

• Alerts v2
• Events v2
• Transaction

Each of these data streams supports multiple cloud inputs—GCS, Azure Blob Storage, and AWS S3. Therefore, system tests need to be added for all three input types within each respective data stream.
