Excessive RPC clients created on connect & page load

[dgabriele]

Describe the bug

Whenever you connect a wallet (e.g. via Keplr), Graz is clearly creating an unnecessary number of RPC clients internally, probably via CosmWasmClient.connect. If you look at network activity in the browser, you'll notice at least 4 concurrent requests to the RPC provider, targeting its "status" endpoint, which is what the CosmWasmClient.connect method automatically does each time it is called. This is not good. Depending on the RPC provider, this can trigger an HTTP 429 rate limit error. Instead, you guys really ought to manage a singleton client and make use of the batch RPC client available in cosmjs.

To Reproduce

Steps to reproduce the behavior:

1. Open dev console in browser.
2. Navigate to your demo app.
3. Open "Network Activity" tab
4. Connect wallet via Keplr.
5. Notice the exessive XHR requests sent to the RPC's "status" method.

Expected behavior

There should be only one request to the "status" method globally.
