Print a . while loading (instead of implementing a spinner)

[pmuens]

We should append a . in the terminal while Serverless is loading / doing it's thing (e.g. deploy a CloudFormation stack) instead of printing a message each time.

This might help with the implementation:

Otherwise we can print a ., use the readline module to see how many . are already printed (e.g. 4) and then just add another . and repeat. This way we don't have to keep variable to store how many . are already printed..

So for a first simple implementation we could create a short method that prints a message first and then in a defined timeframe prints . . . . . .

So e.g.

Waiting for Cloudformation deployment . . . . . . . . . . . . . . . 

What do you guys think about this? @tobyhede would be interesting to get your opinion

Imho this should work for the implementation: process.stdout.write(chalk.yellow('.'));

Sounds like a good, minimalistic solution! 👍
