release: v0.5.0 regenesis changesets

Bump minor versions

regenesis: 0.5.0

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

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.

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.

refactor(contracts): Rename deployAndPostDeploy to deployAndVerifyAndThen

The dockerfile was failing on the step due to `python` no longer
existing in the alpinelinux archives. This commit updates the
version of `python` to `python3` so that the deployer image
can build properly. Also update the integration-tests image
to use python3 and the deployer entrypoint script to use python3

Update the regenesis surgery tests to use the `GenesisJsonProvider`.
Remove hardhat to test with and use `ts-mocha` instead.

Repair the latest known queue index on startup to prevent
skipped deposits

This will ensure the `builder` is built first so that other
services that depend on the `builder` do not pull a remote
`builder` image.

Adds the http header 'User-Agent' to the creation
of ethers providers across the services to allow
for more visibility into what services are sending
requests.

Also delete dead imports since they were breaking
during linting.

Move the instantiation of the providers to earlier
in the script so that they can be used to check the
chain id before doing any slow disk reads of giant json
files.
