List accounts like nodes or apps

[jorgecuesta]

Is your feature request related to a problem? Please describe. Currently the only way to list all the accounts is query /v1/query/state and read from there.

Describe the solution you'd like Endpoint on the current rpc spec, like /v1/query/accounts Payload:

{
  "height": 1,
  "address": ["add1", "add2"] or "address" // optional
  "page": 1,
  "per_page": 1000
}
