Updating `azk-dev` and other related dependencies

[nuxlli]

The main contribution on this PR is updating the azk-dev lib. This brings, among other improvements, babel 6.x version. In few words, those changes on babel make the source code transpilation process more modular.

• Updating azk-dev:
  • Changes on azk-dev modules calls, from azk/gulp to azk/lib/gulp, as instance. The former pattern is still supported but has been deprecated: 30409279067a94ebc6e50e1cccfe2f1e4d569861;
  • The order in which the chai plugins are loaded was changed. Now, it's possible to combine chai-as-promised and chai-subset. This is not part of azk anymore: 03658bc09c4d2c390b650cd5e9709075386bc475;
  • Replacing the system of support to generators (directly in the it methods) with a system from azk-dev, which is simpler and better supported 03658bc09c4d2c390b650cd5e9709075386bc475;
  • In bluebird > 3.0, the method promisify was changed and no longer supports the return of multiple actions (aka: Array expansion). This has caused a big impact and led to replacing many nfcall and nbind by direct calls to promisify with the option { multiArgs: true } ec5f0e6998f7ce13f8e41aa84c2c5182caff97ea;
  • While solving the previous problem, we've noticed a problem with the error handling during the VM start on agent. It was fixed, so now it's easier to identify them e67e8e360e0d5232aa3366166602eeb0d8f7a87e;
  • Finally, for a matter of simplification and better support to the modules scheme from ES6, the use of the instructions export, export default and import was improved 30409279067a94ebc6e50e1cccfe2f1e4d569861;
• Updating lodash:
  • template now generates a "compiled template", returning a method to expand it. The src/utils was updated to attend this new API. More at c5f532f60c2d636520ce42f5b80c517c2c33718f;
  • By default, flatten no longer does deep flaten. To do so, the option true must be passed. In this case, the change was bigger once the problem occured in src/cmd/start.js and it was noticed there were better approaches in the class Manifest to get the system list and its dependencies.

  • While solving the problem with template, it was identified an issue on the specification of ManifestError which turned the debbuging process more harsh. To solve this, a type was added to the error in order to identify it adc9e5f12bcd473ec643fe5c00ae7d442e316a1f;
  • A change in the function merge brought a problem in processing the parameters to be sent to the Docker during the execution of the steps of provision or execution of a azk shell. A change to "assign" fixed the problem: e67237a15fd4a53849140858047dfc01ba4a217d;
• Updating insight-keen-io, removing support to promises. Instead, default node callbacks are used b60247a3a9e7f8ce93bd3ce9249310f4282efd17;
• Other updates with minor impact: archiver, crash-report-sender, docker-registry-downloader, file-async and inquirer f25e06736fc66bf3ccc552cd431bd050b8e4804b;
