Add ability to run Optimism fixturenet with external L1 endpoint (#273)

* Remove unnecessary todos

* Set option to log commands in shell scripts

* Replace fixturenet-eth dependency with wait on endpoint

* Skip lighthouse node dependency check

* Update all services in the stack

* Use debug flag to enable shell commands logging

* Add bash in op-batcher container

* Update mobymask-v2 instructions

* Update fixturenet-optimism instructions

* Add descriptions for services

* Move ts files to container-build

* Take L1 RPC endpoint from the env file

* Add dev mode restriction for editing env file
