IPFS Node info every Staking Era

[charmitro]

We want to contain these info on an event every era

pub struct IpfsNode {
	pub peer_id: String,
	pub addr: String,
	pub avail: i32,
	pub max: i32,
	pub files: i32,
}

I cannot find a way to put a String as an Event argument. Should we emit the peer_id and addr as vec<u8> and the node_listener converts them to String?

In Substrate we always use Vec<u8> for strings.
