[Issue] azd up should create a new directory for better dx

[piizei]

Describe the bug

Like every other common developer cli-tool (like git), azd should create the directory when azd up is ran.

Expected behavior

Create a directory with the name of the template

Environment Information on your environment: azd version 0.3.0-beta.1

[jongio]

We'll want to consider side effects of doing this, like azd up runs multiple commands assuming current directory, if azd init puts in a subfolder, then we'll need to execute sub commands in the context of that new subfolder.

This should be achievable now that we have --cwd option.

Needs investigation and discussion on what other CLI's/tools do.
