Add optional flags to provides endpoints

[rpbritton]

Issue

Since provides endpoints can be non-optional, can the default value of optional is false, these endpoints are assumed non-optional.

Solution

Set optional flag on provides endpoints to indicate correct optionality.

I'm not sure we should make those endpoints optional because it would be important to warn the users to properly set up the monitoring of the database to avoid different issues not being correctly caught.
