Handle restarts for services in fixturenet-optimism stack (#282)

* Check existing L1 contracts deployment

* Rename volume used for generated L2 config

* Check for existing L2 geth data directory

* Cross check existing L2 config against L1 deployment config

* Verify sequencer key in existing L2 geth data directory

* Add instructions to troubleshoot corrupt L2 geth dir

* Separate out instructions to run L2 with external L1

* Update docs
