PR suggestion: withRetry wrapper

[LiranBri]

Hi, I wrote an higher-level function util withRetry which makes the usage of the library very easy and also supports promises.

this is what I wrote:

const retry = require('retry');

function withRetry(callback) {
  return (...args) => {
    const operation = retry.operation({ retries: 5 });

    return new Promise((resolve, reject) => {
      operation.attempt(async function (currentAttempt) {
        try {
          const result = await callback(...args);
          resolve(result);
        } catch (err) {
          console.log(`attempt #${currentAttempt} failed. error: ${err.message}`);
          if (operation.retry(err)) {
            return;
          }
          reject(err);
        }
      });
    });
  };
}
module.exports = withRetry;

now any function could be enhanced with retry logic using a single line. e.g:

async functuin myFunc(a, b) {
   // .. bla bla async logic .. 
   return a + b
} 
module.exports = withRetry(myFunc);

if it feels useful, I can make the code more generic, and contribute as PR

isn't that already mostly done with wrap function, although different signature?
