R4R: update pricefeed module rest endpoints (#359)
* query get price implemented - /pricefeed/price/xrp:usd * query rawprices implemented - /pricefeed/rawprices/xrp:usd * refactored to QueryWithMarketIDParams, added rest logic for QueryOracles * new query get oracles implemented for cli and rest - /pricefeed/oracles/xrp:usd * tx postprice implemented - /pricefeed/postprice/{MsgPostPrice} * updated contrib with post-price examples and added to README * added cliCtx.WithHeight(height) and removed import comment

Format the base request in create-cdp.json. You'll need to update the 'from', 'chain-id', 'account_number', 'sequence', and 'gas' as appropriate. Then, populate the CDP creation request's params 'owner', 'collateral', and 'principal'. An example formatted base request can be found in `example-create-cdp.json`.
|
||||
Now we'll create an unsigned request, sign it, and broadcast it to the Kava blockchain via the rest server. Note that if you're using the mainnet or testnet, the host IP address will need to be updated to point at an active rest server instead of http://127.0.0.1.

### Post market price example request
|

|

Note that only market oracles can post prices, other senders will have their transactions rejected by Kava.

Format the base request in post-price.json. You'll need to update the 'from', 'chain-id', 'account_number', 'sequence', and 'gas' as appropriate.
