implement basic netlify functions:list command

[swyxio]

- Summary

its small, people want to check that their functions are properly formatted. theres more potential for local validation (functions doctor?) generally.

closes #209

pulling out the functions parsing to a separate file also helps us write other functionality.

- Description for the changelog

run ntl functions:list to see your locally correctly configured functions.

Looks good. We should probably add one more column here: Live (or whatever word)

The live column is true/false and specifies if the function is currenly live on the site or just local (undeployed) right now.

The live functions are included in the https://open-api.netlify.com/#/default/getSite endpoint

Example https://github.com/netlify-labs/oauth-example/blob/master/src/App.js#L155-L156

cool, TIL you added the Functions thing to your app

the word live i think collides with netlify dev --live. i'd go for deployed altho its a longer word.

i wonder if we can hash the function to understand if this specific version of the function has been deployed.

hmm, this swagger doesnt seem to have the available_functions that you us

[swyxio]

added the deployment check

edited to flip the colors

[swyxio]

reverted to table format. chalk seems to mess it up so i opted to remove chalk.

nice! Looks good.

Yes 😢. There is some serious syncing that needs to happen with API & the API spec.
