Add ls-lint to sfdx projects #2160

Is your feature request related to a problem? Please describe.
No

What are you trying to do
Standardize the way sfdx projects enforce file/directory naming conventions.

Describe the solution you'd like

• sfdx projects must be created with ls-lint
• sfdx projects must have a standard set of ls-lint rules.
• rules must be overwritten
• must be called by an sfdx hook (pre commit|push prefarably)
• include ls-lint in the lint script. I want to run es-lint and ls-lint when typing npm run lint
• it could be released as a plugin called @salesforce/plugin-ls-lint and later, based on telemetry data, you can decide if it makes sense to add it, or not, in the list of core plugins.

https://ls-lint.org/

You could create a new package that bundles ls-lint with your pre defined set of rules, and then add it in the dev dependencies of sfdx projects.

Benefits:

• less time reviewing PRs to check if files and directories are following naming conventions
• ease project onboarding
• avoid deploying metadata that arent following naming conventions

Describe alternatives you've considered
I can add ls-lint to every sfdx project I work on... but I would have to spend time convincing people about its benefits, and every sfdx project could end up having different set of naming conventions.
