[\#578](https://github.com/Kava-Labs/kava/pulls/578) Add v0.3 compatible REST client that supports
[\#629](https://github.com/Kava-Labs/kava/pulls/629) Add CDP collateral type as a field for CDPs and collateral parameters.
### Breaking changes
* CDPs have an additional field, Type, which is a string that represents the unique collateral type that this CDP holds. This enables, for example, a single denom such as 'bnb' to have two CDP types, 'bnb-a' and 'bnb-b'.
* CollateralParam has an additional field, Type, which is a string that represents the collateral type of CDPs that this collateral parameter governs. It must be non-empty at genesis or when altering CDP fields. It is UNSAFE to alter the type of an existing collateral param using unchain governance.
* CDP messages must specify the collateral type 'bnb-a', rather than the denom of the cdp.
* In the incentive module, fields previously named `Denom` have been changed to `CollateralType`. Previously, 'Denom' was validated to check that it satisfied `sdk.ValidateDenom`, now, the validation checks that the `CollateralType` is not blank.
* Incentive module messages now require the user to specify the collateral type ('bnb-a'), rather than the denom of the cdp ('bnb')
