[p3] Several query commands in "distribution" fail to support "normal" output, all the returns of these commands are "json" format.

[shilei-wang]

These commands are :
iriscli distribution delegator-distr-info
iriscli distribution delegation-distr-info
iriscli distribution validator-distr-info

---

To Reproduce

for example, in non-json mode:

iriscli distribution delegator-distr-info faa1ugvhffeqfsps8huydgn9ajtgxh8kgszuduukrv --chain-id=shilei-qa
[
{
"delegator_addr": "faa1ugvhffeqfsps8huydgn9ajtgxh8kgszuduukrv",
"val_operator_addr": "fva1ugvhffeqfsps8huydgn9ajtgxh8kgszucdke7t",
"del_pool_withdrawal_height": "1576"
}
]

Currect version：
v0.14.0

These three apis don't seem to make much sense, so should we consider removing them? @haifengxi

[haifengxi]

Let's drop these three subcommands @chengwenxi
