Merge parallel launches

[drewrichardson2]

We run our tests in parallel in circle-ci using the cypress-orbs. We've got a couple different reporters configured so I use a custom cypress runner that also configures report portal. Providing the isLaunchMergeRequired option as true does not work and providing autoMerge as true causes tests to never finish inside of Report Portal. I'd like the launches to be merged once they all finish in parallel, similar to this issue here on another agent: reportportal/agent-net-specflow#35

This issue is created out of this post in slack here: https://reportportal.slack.com/archives/C2GTJTTNH/p1607090566045400?thread_ts=1606931183.021600&cid=C2GTJTTNH

Here is my configuration file for cypress/reportPortal. I've taken the merge code out for now as it wasn't working.

const CYPRESS = require('cypress');
const FS = require('fs');
const GLOB = require('glob');
const REPORTPORTAL = require('@reportportal/agent-js-cypress')
const ARGS = process.argv.slice(2)
const REPORTERCONFIGFILE = 'cypress/reporters/reportPortal.json';
const TAG = ARGS[0].toUpperCase()
const GROUP = ARGS[1]
let environment = TAG.includes("staging")?'staging':'daily'
let config;

const DATA = FS.readFileSync(REPORTERCONFIGFILE, 'utf8') 

config = JSON.parse(DATA)
config.reporterOptions.token = process.env.RPP_TOKEN
config.reporterOptions.launch = TAG + " " + process.env.CIRCLE_SHA1.substring(0,8)
CYPRESS.run({
  reporterOptions : config.reporterOptions,
  parallel: true,
  record: true,
  browser: "chrome",
  headless: true,
  key: process.env.CYPRESS_RECORD_KEY,
  tag: TAG,
  group: GROUP,
  config: {
    baseUrl: environment,
  },
  reporter: "@reportportal/agent-js-cypress",
  env: {
    grep: "@Flaky",
    invert: true}
  }).then(
    () => {
      process.exit(0)
    });

Perhaps we could set the launch id to the commit sha somehow so it's always unique, then once it gets to report portal it detects they're all the same and merges?
