Create publishToNpm jenkins library

[gaiksaya]

Node JS clients will be published on NPM under @opensearch-project namespace. Component that can be used for this library testing is JS client: https://github.com/opensearch-project/opensearch-js

Acceptance Criteria:

• The library needs to be generic enough to accept any JS artifact
• Publish to NPM without manual intervention

Putting some research details out:

NPM packages can be easily published using npm automation tokens specifically designed for CI/CD systems. More details: https://docs.npmjs.com/creating-and-viewing-access-tokens#creating-tokens-on-the-website
The package should allow auto publishing via tokens. Good article read

We need to create a new automation token (one time effort) and then use it in our CI/CD to publish the packages. The project needs to have a .npmrc file with below details:

//registry.npmjs.org/:_authToken=${NPM_TOKEN}
