Reduce the installing nodes time

[shibd]

At present, when using openchaos, if you want to install dledger, you will pull the source code for each node and rebuild it, which takes a long time, and sometimes it may not be successful (network problem).

It can be modified to build first in the controller, and then distribute to each node

I think this is a good suggestion. You can help implement it and contribute it in OpenChaos.

You can change the title to English next time, so that others can refer to it.
