Review component and update as this is an example of node.js component

[stas-fomenko]

What could be done:

• review and update code according to PS best practises (e.g: get rid of MagentoClient here

  petstore-component-nodejs/verifyCredentials.js

  Line 16 in a728a8b

  const client = new MagentoClient(this, credentials);

  petstore-component-nodejs/verifyCredentials.js

  Line 1 in a728a8b

  const MagentoClient = require('./lib/petstoreClient');

  )
• update README according to https://github.com/elasticio/professional-services-best-practices/blob/master/templates/readme-template.md
• add helplinks
• remove html tegs from notes as this is currently not supported by frontend
  
• maybe add circle.ci as an example
• use npm audit as an example
• etc

Or perhaps move away from petstore to the example component: https://github.com/elasticio/example-component
