connect error

[chengwenxi]

Hi, the rest-server and client command will create a new HTTP rpcclient for each requst(e.g. /query/stake/candidates), much requst will cause connect error(cannot assign requested address)

[kidinamoto01]

Gaia rest client will create a new HTTP Client for every query, this can lead to connection overflow easily.

@melekes any thoughts on preventing this?

^^

Do we want to reuse the same rpcclient instance for all calls (was there a particular reason for the current implementation not reusing the same client)?

Yes let's reuse it for all the calls. The current implementation was hacked together in haste by the UI team in order to unblock the UI team :P

Should be fixed on develop
