gas-oracle: implement and test 

This commit adds the `gas-oracle` which is an offchain entity
that sends transactions to L2 to update the gas price. It must
be configured with a private key as the `OVM_GasPriceOracle`
is owned.

The `gas-oracle` is added to the changesets setup.

Tests are included as well as CI. Dockerizing will happen
in a follow up PR.

# gas-oracle
This service is responsible for sending transactions to the Sequencer to update
the L2 gas price over time. It consists of a set of functions found in the
`gasprices` package that define the parameters of how the gas prices are updated
and then the `oracle` package is responsible for observing the Sequencer over
time and send transactions that actually do update the gas prices.
### Generating the Bindings
Note: this only needs to happen if the ABI of the `OVM_GasPriceOracle` is
updated.
This project uses `abigen` to automatically create smart contract bindings in
Go. To generate the bindings, be sure that the latest ABI and bytecode are
committed into the repository in the `abis` directory.
Use the following command to generate the bindings:
```bash
$ make binding
```
Be sure to use `abigen` built with the same version of `go-ethereum` as what is
in the `go.mod` file.
### Building the service
The service can be built with the `Makefile`. A binary will be produced
called the `gas-oracle`.
```bash
$ make gas-oracle
```
### Running the service
Use the `--help` flag when running the `gas-oracle` to see it's configuration
options.
```
