feat: Change output of removeorder command/grpc call

[raladev]

Reason

UX improvements

Task 1

Change current output of removeorder to more useful.
As user I want to know status of the operation, but instead of that I got info about amount in hold (it is additional information, not main)
It seems removed qty should be returned in response + remained qty if it was partial removal + qty in hold if it exists:
{
removedQty:5;# qty that was successfully removed
remainingQty:7;# remaining qty after partial removing
quantityOnHold:5; # qty in swap, but it will be removed if swap fails
}

Task 2

Add Text output to xucli for removeorder command. Now it returns only json.

Draft:

• order "id" with qty "qty" fully removed - if remained = 0, and quantityOnHold = 0;
• order "id" with qty "qty" partially removed, remained qty = "qty" - if remained != 0, and quantityOnHold = 0;
• order "id" with qty "qty" partially removed, qty on hold because of swap process = "qty" - if remained = 0, and quantityOnHold != 0;

Noticed that today too. Currently only two cases:

1. quantityOnHold: 0

testnet > removeorder a8d8ffb0-acd0-11ea-9bb4-378737f17cd2
{
  "quantityOnHold": 0
}

->

testnet > removeorder a8d8ffb0-acd0-11ea-9bb4-378737f17cd2
Order a8d8ffb0-acd0-11ea-9bb4-378737f17cd2 successfully removed.

2. quantityOnHold: X

testnet > removeorder a8d8ffb0-acd0-11ea-9bb4-378737f17cd2
{
  "quantityOnHold": 123
}

->

testnet > removeorder a8d8ffb0-acd0-11ea-9bb4-378737f17cd2
Order a8d8ffb0-acd0-11ea-9bb4-378737f17cd2 partially removed, remaining quantity on hold: 123
