Hi,

I have a problem with an SQL Server Data Source, we have multiple instances, but Grafana throws an error.

No matter how I type adress:

```
sqlserver\instance
or sqlserver\\instance 

```

It drops an error:

```
Validation error, invalid URL: "sqlserver\\instance"
Validation error, invalid URL: "sqlserver\\\\instance"
```
