[TestBot][Linux] Deploy on Azure using Azure Pipelines

[ParadoxARG]

This PR is based on #47 and #44. We will rebase it after they are merged.

Description

Create deployment template and scripts to deploy TestBot on an Azure Linux Host.

Steps to configure the Pipeline

We are going to use the Windows deployment Pipeline created on #44.

1. Clone the Windows deployment Pipeline.
2. Modify the Create Bot Resource Group task to point to the linux template. Replace the BotName, AppId and AppSecret parameters with the pipeline variables.

3. Remove the Compress Bot Source Code Powershell task and replace it with a Command Line task with the following code:

Move $(System.DefaultWorkingDirectory)\libraries\testbot\deployment-scripts\linux\* $(System.DefaultWorkingDirectory)\libraries\testbot

git config --global user.name "BotBuilderDotNetPipeline"

git config --global user.email BotBuilderDotNet@Pipeline.com

git init

git add .

git commit -m "Add bot source code"

git remote add azure https://$(AzureDeploymentUser):$(AzureDeploymentPassword)@$(TestBotName).scm.azurewebsites.net:443/$(TestBotName).git

git push azure master

Also, set the Working Directory on the advanced tab to libraries/testbot.

4. Remove the zip-push deploy line from Create Directline Azure CLI task.

I think that the steps' numbers are wrong. Last step should be number 4 instead of number 1

Can you blur the Azure subscription in the first image?
