Plan / Package subscription feature for Builder

[predominant]

Describe the Enhancement:

Allow users to opt in for notifications / alerts about activity on a plan.

Describe the Need:

This is universally useful to all users on any builder instance. Users that want to be notified of new builds available, new promoted packages, or special notifications regarding the package can be reached via this system.

General user benefits:

• Get notified about selected events for selected plans:
• Just promotion notifications on core/glibc
• All new builds for myapp/backend
• Receive special announcements regarding subscribed packages

Administrator / plan author benefits:

• Reach users for breaking changes
• This is a big need in core-plans at the moment
• A way to send notifications (optionally emails, based on user preference?) when breaking changes are coming through the pipeline

Notification Levels

I can see this being useful, but also noisy. Package notification is going to have to be a tiered thing. Much like the way Github allows increasingly noisy notifications to be sent to users based on their preferences for a repo.

Increasing, such as:

• Breaking changes
• Only Promotions to stable
• All promotions (any channel)
• All builds

Can We Help You Implement This?:

I'm relatively busy on other community bits. And am not as confident as I need to be with my Rust level of skill as yet to contribute to this, personally.

This is a FANTASTIC idea and very much needed. We should not expect casual users of Habitat to be reading each minute detail of every PR that comes through. Great idea @predominant !!!
