Is there a way to pass the Redis credentials to the write and read function instead of the Spark session?

Hi,

Instead of passing the Redis credential in the spark session creation moment, Is it possible to pass the info at reading or writing time?

Something like:
```
conf = df.write \
            .option("url", self.url) \
            .option("user", self.user) \
            .option("password", self.password).save()
```
