[Feature] Improve convenience for skipping historical messages when creating a new consumer group

[0xCAFEBABE0]

Is Your Feature Request Related to a Problem?

When creating a new consumer group, if we want to avoid consuming historical messages, the current methods are either:

• Manually skipping messages through the Dashboard, or
• Using mqadmin to clone the consumer group and then reset the offsets.

Describe the Solution You'd Like

For topics that have existed online for a long time and continuously accumulate large amounts of data, there is often a need to skip historical messages when creating a new consumer group. Currently, this can only be achieved using mqadmin commands.

Describe Alternatives You've Considered

While these methods work, they can be cumbersome in certain scenarios. Would you consider providing a more straightforward way to achieve this, such as an option to directly skip historical messages when the consumer group is created? This would greatly improve usability and efficiency.

Additional Context

It would be helpful to introduce a more user-friendly and streamlined solution for skipping historical messages when adding a new consumer group, without relying on manual mqadmin operations.

When the consumer group starts, use the seek method to select the offset.
