Pass HttpContext to Session.commit and Session.initiate

[codmajik]

This will make it possible to extend a session configuration based on the request.

My current use case:
I am an application that provides subdomains for a bunch of kiosks when a customer logs into one they are logged into all of them, now this is simple enough to do, (just set the domain in the session cookie config to the base domain) the curve ball is that, some kiosks want their own on a custom domain, so I need to reset the cookie config when the request comes from these custom domains.

How I would have used it

const sessionCommitFn = Session.prototype.commit
Session.macro('commit', function (this: Session, ctx: HttpContext): Promise<void> {
  if (ctx.isCustomDomain) {
    this.config = { ...this.config, cookie: { ...this.config.cookie, domain: undefined } }
  }

  return sessionCommitFn.call(this)
})
