Support LACP networking configuration for EKSA BareMetal

**What would you like to be added**:

EKSA Bare Metal documentation shows Advanced Bare Metal Cluster Configuration [1]. There are no docs on LACP networking Configuration. Workaround [2] [3] from Cilium GitHub issue with few details.

[2] https://github.com/cilium/cilium/issues/18706
[3] https://github.com/cilium/cilium/issues/18706#issuecomment-1031572546

**Why is this needed**:

- High Avaialbility, Load Balancing, Scalability and to support High performance networks.
- Example: Telco or Streaming use cases.

Start with the Advanced Bare Metal Cluster Configuration documentation linked as [1], then read the configuration details and workaround in the Cilium issue and comment linked as [2] and [3]. Document the supported LACP networking configuration for EKSA Bare Metal, including enough setup detail for the stated high-availability and performance use cases.
