* feat(providers): return a PendingTransaction from send_tx calls
* feat(providers): expose the internal provider to all middlewares
* fix(middleware): use the returned PendingTx instead of using a hash
* fix(contract): use the pending tx returned value
Note1: To support that, we need to clone the tx when sending in order to make lifetimes work out
Note2: Multicall does not support that feature
* fix(ethers): adjust examples
* chore: fix provider test
* chore: fix celo test
BREAKING CHANGE
* fix(signers): make Signer send by blocking on Ledger calls
* fix(providers): use Arc in WS impl to allow cloning
* feat(middleware): add geometric gas price escalator
* test(middleware): ensure that we can still stack everything up
* fix(middleware): default to tokio/async-std
* chore: fix clippy
* docs(middleware): add docs and rename middlewares
* chore: fix doctests
* feat: add linear gas escalator

* feat: add constructors to gas escalators
* feat(provider): allow specifying a default polling interval param
This parameter is going to be used for all subsequent client calls by default. It can still be overriden with the internal
`interval` calls
* feat(contract): replace reference to Client with Arc
* feat(abigen): adjusts codegen to use Arcs
* fix(ethers): adjust examples to new apis
* fix(provider): return TxHash instead of PendingTransaction on tx submission
Returning a PendingTransaction allowed us to have nice ethers.js-like syntax where you submit
a transaction and then can immediately await it. Unfortunately, now that we use Arcs and not lifetimes
this meant that we would need to bind the function call in a variable, and then await on it, which is pretty
bad UX.
To fix this, we revert back to returning a TxHash and introduce a convenience method on the provider and the
contract which takes a tx_hash and returns a PendingTransaction object. The syntax ends up being slightly
more verbose (although more explicit), but the issue is fixed.
* feat: add pending tx type
* feat(pending-txs): implement the full state machine
* tests(ethers): fix transfer eth example
* feat: use the pending transaction struct when deploying a contract
* ci: skip the pending tx test
* chore: fix doctests
