Upgrade bitcoin harness dependency to latest commit
Upgrade backoff to fix failing tests. The previous version of backoff had a broken version of the retry function. Upgraded to a newer comit which fixes this problem.
Upgrade hyper to 0.14 as the 0.13 was bringing in tokio 0.2.24
Upgraded bitcoin harness to version that uses tokio 1.0 and reqwest 0.11
Upgrade reqwest to 0.11. Reqwest 0.11 uses tokio 1.0
Upgrade libp2p to 0.34 in preparation for tokio 1.0 upgrade
Rust fmt automatically groups the imports (from top to bottom) as `pub use` `use crate` and `use`.
There is no need to introduce sections which cause annoyance when auto importing using the IDE.
- Make it the same for Alice and Bob.
- Make it contain a wallet client instead of the `Monero` struct.
Also:
Remove `Container` from inside `Monero` struct. The caller of `new`
can simply ensure that `Container` is not dropped to keep the
container alive.
This makes the `Monero` struct easier to work with, as it just holds
the data necessary to create the different clients created during
`init`, and does not have any lifetime restrictions.
