## What changes were proposed in this pull request?

This patch changes the schema of url from http to https for bintray spark-packages repository. Looks like we already changed the schema of repository url for pom.xml but missed inside the code.

## How was this patch tested?

Manually ran the `--package` via `./bin/spark-shell --verbose  --packages "RedisLabs:spark-redis:0.3.2"`

```
