Comment 6 for bug 1260290

@Raghu

After second thought, I think it's better to stick to following process.
1. set provider options (when none provider is loaded)
2. reload provider (because some options can be set after provider initialization)
3. set address (connect action happens at this point)
4. after connecting to cluster, set some other dynamic options.

point 1,2 are mysql related part, and provider independent. And this issue is fixed in
