What happened?

Description

The Redis receiver has several bugs in its metadata.yaml file where metrics are incorrectly classified as sum when they should be gauge, and some units are incorrect for offset values.

Steps to Reproduce

NA

Expected Result

Several metrics representing current state are incorrectly defined as sum metrics:

• redis.clients.connected
• redis.clients.blocked
• redis.slaves.connected
• redis.rdb.changes_since_last_save
• redis.role

A couple of metrics needs fixes in its unit field:

*offset metrics are marked as unit: "By" i.e., redis.replication.backlog_first_byte_offset and redis.replication.offset

Ref: https://redis.io/docs/latest/commands/info/ to now about the metrics

Actual Result

• metrics should be marked as gauge and not sum for the aforementioned metrics
• redis.replication.backlog_first_byte_offset and redis.replication.offset should have unit: 1?
