Allow users to create staking vaults

[0x-r4bbit]

Once the wallet connection from #2 is implemented, the next step is to allow users to create vaults for the protocol.
There are various ways to do this:

• Either use the vault factory we've deployed on a testnet (this is the easier version as it would be a simple function call), or
• Implement the deployment "from scratch" via just the front-end

For starters, the first option will likely yield results faster.
The second option however, should probably be the final version of this.

One thing to add here:

Vaults have to be registered with the staking manager proxy.
When the second option is implemented, this can be abstracted away nicely via UI.

Pleasem, can you link/share the testnet deplyment addresses and ABI?

One thing to be aware of is that there's currently a bug in the reward system: vacp2p/staking-reward-streamer#102

This will be fixed and the contract will be upgraded, so the addresses will stay the same.
