Add multipart

[mnishizawa]

Adds support for multipart forms for file upload via a service call.

Note: a lot of the files here are simply reformatted though I didn't touch them and never opened them. Not sure if that is happening in the precommit hooks but I thought I would bring it up that I did not reformat those files.

I don't see any other test frameworks for apis that support multipart form submission for file upload.

Test plan Definition test has been added to the rest of the definitions tests.

When I use the step definition, "[I ]set request multipart body from ", the request will create a request for a multipart form submission.

Sample fixture:

'use strict'

const fs = require('fs')

module.exports = () => ({
    "errorLog" : fs.createReadStream(__dirname+"/sampleErrorFile.txt.zip")
})

@mnishizawa, thank you for this contribution, for the updated files you didn't touched, that's probably because you're using npm instead of yarn, this repo provides a yarn.lock. There's a git hook which format files, because npm didn't used lock file, you may have a different prettier version which formatted code differently. Is it possible that you switch to yarn and re-format the code please?

[mnishizawa]

When I commit the husky hooks appear to still be running npm. Is there something I need to do to tell it to run yarn instead?

[plouc]

Sorry, I meant just running the install through yarn, npm should be fine after that, it's just to lock deps.

Ok, files should be updated now, one of the snapshot tests failed. Any guidance on how I may have affected that test since I didn't change anything in the snapshots extension?

[plouc]

Fail was due to a timeout, just restarted it, and it passed.

[mnishizawa]

Cool. Anything else you would like me to fix or change?

[plouc]

Nope, LGTM, thank you!
