Azure: exclude development dependency files when packaging functions

[mydiemho]

.funcignore is not being used so have to add the ignore files
to the exclude section in serverless.yml

What did you implement:

Update azure-nodejs/serverless.yml to exclude vscode settings and local.settings.json in function artifact.

How did you implement it:

How can we verify it:

sls create -t azure-nodejs -p myApp
cd myApp
npm install
sls deploy # verify that those files are not uploaded to the app
