Request: load balance in ABACUS

[kirk0830]

Background

as mentioned by @QuantumMisaka for times, if the system to simulate is highly heterogeneous, he observe it is better to rotate the axis that is the norm of vacuum layer along y instead of z (the most common choice). I tested and find there will be 100% improvement in performance:
vacuum along z

vacuum along y

Describe the solution you'd like

I guess there must be some algorithm is poorly load-balanced, the manual rotation on system actually means balancing by human...
However, for those users do not know about this feature, they may doubt about performance of ABACUS.
I suggest do the automatic load balance, in this case, the simplest solution would be a rotation on system by ABACUS its own.

PR #5898 may solve this issue.

It's not totally realted to #5898, but we will try to fix this in future. I will move this to discussion.
