[FEAT] - confirm shard relocation

[coola007]

Hi:
chrome ext :
Using shard reroute operations, clicking on a shard cannot be canceled, only refreshing the page works.

Reroute operations do not provide prompts, and making a mistake can be extremely risky

So this action is very warning...
This operation needs to be handled with great care and requires prompts; otherwise, the risk of making a mistake is very high.

You can cancel by clicking on the same shard again.

A confirm makes sense, i will look into this.

Fixed in 1.0.8. Thanks!
