Summary

Added restricted_balances field to the cf_account_info_v2 RPC. No idea if this breaks things on the web side.
The restricted balances is a map of Eth addresses and amounts.
The available balance = balance - bond, So i did not add it to the struct because the info is already there.

Should we add something to the bouncer that checks this new field?

PRO-834 Rpc for restricted SC FLIP balances

The front end needs to be able to display available/restricted funds.

See this conversation for details:

daniel said in WEB-430:

I agree this would be useful! There is no rpc yet for the redeemable amount. Bound address should be easy. I think the best thing would be to add this to the accountInfo rpc (or maybe a new endpoint - any preference??)

It's bit more complicated than this I'm afraid.
