Add savings strategy (#1290)

Browse Source 
* Add basic savings strategy

Supports ukava

* Use clearer error message for ErrInvalidVaultStrategy

* Add invariants

* Separate specific vault/all vaults query, update depositor inconsistencies

* Update swagger

* Use single bkava AllowedVault for all bkava variants

* Do not use allowedVault.Denom for value

* Fix vault balance query

* Update query to list bkava vaults

* Add vaults query doc

* Update grpc query test with no supply

* Add earn hooks

* Handle errors

* Update outdated doc comments, make getAllowedVault_Raw private

* Fix outdated comments, lints

* Fix comment maths

* Use AccAddressFromBech32 to validate message addresses
