CLI `config create` command for generating new project configs
I think it'll be useful to add a create subcommand to config that allows the user to create new configs from scratch. Here's examples of how this might be use:
circleci config create [flags]
--executor string Can be 'docker', 'machine', or 'macos'. Defaults to 'docker'.
--template string Path to a template file to be used when creating config.
I would image running `circleci config create` with defaults would:
1. Create the `./circleci` directory if it doesn't exists.
2. Create the file ./circleci/config.yml` if it doesn't exists.
3. Create a starting config like below:
- image: cibuilds/base:2018.10
name: "First Step"
command: echo "Run a Bash command."
When adding a new project to CircleCI, the webapp shows a config (very verbose though) that the user could use for that project based on language. In addition to or instead of `--template`, we could have a language keyboard that pulls that same config for the user to use it as a staring point.
