Allow multiple RPC urls

Components

steem.api.setOptions function

Proposal

Allow user to provide multiple RPC API urls for fallback.

Mockups / Examples

Current API:

steem.api.setOptions({ url: 'wss://steemd.steemit.com' });

New API:

steem.api.setOptions({ urls: [
  'wss://steemd.steemit.com',
  'wss://steemd.steemitdev.com',
  'wss://node.steem.ws'
] });

Benefits

Since architecture of the steem network is distributed and community run by design, it's not unusual to have one or more public RPC API nodes unresponsive for some amount of time. Any serious project built on top of steem blockchain will undoubtedly run it's own api node for reliability, but small community run projects usually don't have resources to do so and rely on public API nodes. It would be very beneficial for such projects to have the option of providing array of fallback urls to use automatically when main node is unresponsive.
