How should we change default config values in charms?

[Jorge O. Castro]

Hi everyone,

See: https://bugs.launchpad.net/bugs/1373862

This morning Marco proposed that we change the default dataset-size
from "80%" of the memory to "128M".

Ryan thinks that before we make a default change like this that we
should discuss the implications, for example, if you have an existing
Juju MySQL deployment, and say you want to replicate that in another
environment, the default change is an unexpected surprise to the user.

I am of the opinion that MySQL is one of the first services people
play with when trying Juju and that the charm not working ootb with
the local provider is a big papercut we'd like to fix.
