Remove Travis files and add build tasks in Azure DevOps about botbuilder-community-js

[iMicknl]

Would be great to have Azure Pipelines configured for a 1.0 release. I saw that botbuilder-dotnet is using a develop branch and CI/CD on Azure Pipelines, maybe we can 'steal' their process partly.

What would a definition look like? Something like this?

Build Pipeline

Trigger: *

Tasks:

• Install Node.js (10.x)
• npm install
• Run lerna (build all packages)
• Run ESLint (all packages)
• Run mocha tests (all packages)

We can even decide to release a daily build on a private MyGet, but I guess that would be overkill for the scenario and usage at the moment.. Or publishing a @next tagged build on NPM of development.

Release pipeline

Trigger: master (or manual approval?)
Tasks:

• Release to NPM
• Create git tag + release on Github with Changelog

Yeah, @garypretty created an org for us, I just haven’t had the opportunity to convert the repos and set up the pipelines yet. I’ve been in a bit of a holding pattern for 6 months, but now I’m back to being active enough to knock some issues out and make some changes. I’ll try to get this situated in the next week or so.
