Add support for streaming function logs in sandbox

CLI
- Default to disabled with an explicit opt-in --stream-function-logs
- Allow customers to specify a list of function names for which logs should be streamed
- Sandbox with --once should not stream function logs
- Allow specifying a file path to stream all the function's execution log events to.
Display
- Display log events with the "friendly name" of the function in a specific color. Total of 5 colors used in round robin
- Display a timestamp for each log event
- Colors are turned off for file writing.
Functionality
- While sandbox is idle, function logs are streamed in parallel for all the functions as they are executed.
- Log streaming is paused during a deployment and resumes from the time the deployment was initiated to avoid intermingling the logs
- New functions, deleted functions are automatically updated after a deployment, i.e. if customer adds a new function, it's logs will be automatically streamed (if no filter was used)
