Write user "bots" for stress testing.

[PopcornPaws]

Description

In order to automatize stress tests, we should have "bots" that spam the network with requests as users would. It is quite cumbersome and slow to use the frontend app for interacting with the network for stress testing.

Solution

• [x] implement a central authority (faucet)
• [x] automatically register Alice as an operator (running from a simple pc)
• [x] automatically register some operators (these should be deployed beforehand)
• [x] create a ton of guilds - 100, 1000, 10000, 100000 (send create_guild transactions from multiple clients)
• [x] flood the system with join requests (send join_guild transactions from multiple clients at given intervals)
• [x] try to measure how long it takes to be added to a guild

We should add a well funded faucet (that can fund users) and allocate some stakes for the validators in the genesis block.
