R4R: Split GET delegator endpoint

PENDING.md

@@ -5,6 +5,7 @@ BREAKING CHANGES
 * Gaia REST API (`gaiacli advanced rest-server`)
     * [x/stake] Validator.Owner renamed to Validator.Operator
     * [\#595](https://github.com/cosmos/cosmos-sdk/issues/595) Connections to the REST server are now secured using Transport Layer Security by default. The --insecure flag is provided to switch back to insecure HTTP.
+    * [gaia-lite] [\#2258](https://github.com/cosmos/cosmos-sdk/issues/2258) Split `GET stake/delegators/{delegatorAddr}` into `GET stake/delegators/{delegatorAddr}/delegations`, `GET stake/delegators/{delegatorAddr}/unbonding_delegations` and `GET stake/delegators/{delegatorAddr}/redelegations`
 
 * Gaia CLI  (`gaiacli`)
     * [x/stake] Validator.Owner renamed to Validator.Operator
