[Rubrik RSC Metrics]: Add TCP/UDP Input for Rubrik Syslog

### Integration Name

Rubrik RSC Metrics [rubrik]

### Dataset Name

logs-rubrik.system

### Integration Version

0.9.1

### Agent Version

9.1.5

### OS Version and Architecture

Ubuntu 24.04.3 LTS (Noble Numbat)

### User Goal

In an effort to gain visibility into Rubrik, the metrics encompass a wide range. But Rubrik also produces logs, that can be added as a secondary input for this integration. Perhaps it can then be renamed from Rubrik RSC Metrics to simply Rubrik RSC.

### Existing Features

For security reasons, ingesting Rubrik syslog is valuable.

### What did you see?

No logs portion in the integration

### Anything else?

I believe other SIEM platforms have this capability:

Perhaps it might not need much parsing, just enough to get the syslog message out and to be consolidated into one integration
