FIX: Standardise /vaults

Desired

/asgard

https://testnet.thornode.thorchain.info/thorchain/vaults/asgard

1. add "addresses" in the return object

{
	"block_height": 82868,
	"pub_key": "tthorpub1addwnpepq27nhxu3gy72lfhy0dstvtdsp90qjjvq9jczc6hwknhxrz2kgjas7cwvfh0",
	"coins": [],
	"type": "AsgardVault",
	"status": "ActiveVault",
	"status_since": 82868,
	"membership": [],
	"chains": [],
	"inbound_tx_count": 7,
	"outbound_tx_count": 11,
	"pending_tx_block_heights": [],
	"routers": [],
	"status": "Disabled",
        "addresses": []
}

/yggdrasil

1. remove the "vault" object, and make structure same as Asgard:

{
	"block_height": 82868,
	"pub_key": "tthorpub1addwnpepq27nhxu3gy72lfhy0dstvtdsp90qjjvq9jczc6hwknhxrz2kgjas7cwvfh0",
	"coins": [],
	"type": "YggdrasilVault",
	"status": "ActiveVault",
	"status_since": 82868,
	"membership": [],
	"chains": [],
	"inbound_tx_count": 7,
	"outbound_tx_count": 11,
	"pending_tx_block_heights": [],
	"routers": [],
	"status": "Disabled",
	"bond": "2660986008570",
	"total_value": "6915916",
	"addresses": []
}

/pubkey

Current: /thorchain/vault/{chain}/{address}

Desired: /thorchain/vault/{pubkey}

The likely use of this is to find the current active pub keys, then do a search for each pubkey to locate the assets and address. Currently no use to search by address and chain.
