Hard: refactor borrow/borrows and deposit/deposits query (#761)

Browse Source 
* refactor cli borrows query

* rest api feature parity for borrows query

* refactor deposits cli query

* remove deposit/borrow query names from types

* add named deposit/borrow queries back into types

* rest api feature parity for deposits query

* load synced deposit instead of synced balance

* deposits query returns synced deposits

* borrows query returns synced borrows

* refactor querier types

* update comment for accuracy

* add deposit/borrow slice types

* refactor 'borrowed' query

* implement 'deposited' query types

* implement 'deposited' query keeper function

* implement 'deposited' query CLI

* implement 'deposited' query rest endpoint

* update naming conventions to 'total'
