Add options arguments to Redis HLL Metric YAML definition

What does this MR do?

Add options arguments to Redis HLL Metric YAML definition for filtering data in instrumentation class

• Rename extra attribute to options
• Add required options[:events] to RedisHLLMetrics

This makes instrumentation for data from Redis HLL easier using only metric definition YAML file so we don't need a class for each event tracked using Redis HLL.
