feat(backend): WIP M2M

[wobsoriano]

Description

This is a work-in-progress PR for adding Machine-to-Machine requests in the Backend SDK. Soon, you'll be able to do:

From C1:

import { Hono } from 'hono'
import { createMiddleware } from 'hono/factory'

const app = new Hono()

const clerkMiddleware = createMiddleware(async (c, next) => {
  const authReq = await clerkClient.authenticateRequest(c.req.raw, {
    entity: 'any'
  })

  if (!authReq.isSignedIn) {
    throw new HTTPException(401, { message: 'Not authorized' })
  }
  
  const authObject = authReq.toAuth({ entity: 'any' })
  
  if (authObject.entity === 'user') {
    const { userId, sessionClaims } = authObject
    // do something
  }
  
  if (authObject.entity === 'api_key') {
    const { machineId, userId: userId2, claims } = authObject
    // do something
  }

  await next()
})

app.post('/api/protected', clerkMiddleware, async (c, next) => {
  return c.text('Hello from /api/protected')
})

From C2:

const resp = await fetch('https://c1-site.com/api/protected', {
  method: 'POST',
  headers: {
    'Content-Type': 'application/json',
    'Authorization': `Bearer api_key_foobaryeah1234567890`
  },
})
