Make MySql graceful when using gitpod/workspace-mysql on the first run

[apolopena]

The MySql Daemon has a long initialization time and, that process is asynchronous and blocks whatever terminal it hijacks. This results in a two fold issue:

1. The timing of init and command tasks in .gitpod.yml becomes inconsistant.
2. The long wait time without a user message is a bad user experience as the workspace appears to be broken since some tasks freeze and other run out of sync due to the asynchronous blocking nature of mysqld.

*All of this can mostly be fixed by waiting for the MySql port (3306) to be open and notifying the user accordingly.

Fixes required:

1. • Add a MySql initialization message with a spinner and display it wherever the user can see it (i.e not in a tab an unfocused tab). This message should only display when MySql is initializing which will be on the first run of the workspace only.
2. • Refactor the .gitpod.yml tasks to account for mysqld initialization throwing off the order of when tasks run
