Bug: Search form issue - Search should be case-insensitive

[audserraCGI]

Expected Behavior

When using the search form to filter the device list, searching by name/ID should be case-insensitive.

Current Behavior

Searching "device" doesn't allow us to retrieve our mock device called "Device 1"

Additional Information

There's also a pragma warning in the code asking to normalize the filtering:

IoT-Hub-Portal/src/AzureIoTHub.Portal/Server/Services/DeviceService.cs

Lines 59 to 61 in 5541bb3

	#pragma warning disable CA1308 // Normalize strings to uppercase
	filter += $" AND (STARTSWITH(deviceId, '{searchText.ToLowerInvariant()}') OR (is_defined(tags.deviceName) AND STARTSWITH(tags.deviceName, '{searchText}')))";
	#pragma warning restore CA1308 // Normalize strings to uppercase

Currently, IoT Hub query language doesn't provide functions that can be used to query easily the devices (with lowercase, starts_with, contains, ...).

We decided to postpone this implementation until these features are available in IoT Hub query language.
