[Feature] Basic Authentication support for restroom-mw HTTP endpoint

[sigsalerno]

Specifying username:password@host according to rfc3986 to an endpoint basic auth is configured: https://username:password@example.org/post

auth parameters must be added to the axios post request configuration:

restroom-mw/packages/http/src/index.ts

Line 124 in 465614a

const response = await axios.post(url, r);

username and password can be retrived through the URL() constructor
