The response of the RPC endpoint `eth_getTransactionReceipt`
will now return 4 new fields.

- `l1GasPrice`
- `l1GasUsed`
- `l1Fee`
- `l1FeeScalar`

These fields are added to the database as part of the receipt
itself. This means that it is a consensus change as the
serialization of the receipt has been updated. This impacts
the blockhash because the block header commits to a merkle root
of all of the receipts in the block.

Each of the new fields on the receipt exist in the state but
would require an archive node to query for as the values can
change over time.

Have the ethers L2 context helper pass through the
new optimistic ethereum related fields

Breaking change in v0.8.0

Previously the sequencer would call the `syncBatchesToTip` method
as part of its `sequence()` loop. This commit removes that as the
call to `syncBatchesToTip` does nothing for the sequencer currently.
Syncing the batches would be useful for triggering reorgs, but
that functionality does not currently exist. It would be better to
remove this functionality for now as it could potentially interfere
with the locking mechanism introduced in
dfaa8fc.

This will also reduce the amount of time the `txLock` is held, meaning
that less transactions sent via RPC will be blocked and held in memory
while waiting to execute.

This commit adds an addressNames object, which should be used both for
names in the address manager, and naming deployment artifacts.

fix(contracts): Remove unused queue container test code

feat(contracts): Split up managed and unmanaged names

refactor(contracts): Move address names into a single nested object

refactor(contracts): Make address keys similar to values

chore: add changeset

docs(contracts): Add a docstring to deployAndPostDeploy

refactor(contracts): Remove unnecessary contract name

If the Address Manager's name is the same as the contract artifact
we don't need specify the contract name argument.

THE `TARGET_GAS_LIMIT` should be set to 15 million.
This will match what is deployed on kovan and what will
be deployed on mainnet.

Enable the RPC test for `rollup_gasPrices` that
was previously disabled due to how the gas pricing
scheme was changed in `v0.5.0`.
