A 1.0.0 release!

This marks the 1.0.0 release of Fenzo.
There are no changes in this release compared to 0.13.8.

We plan to keep the existing API compatible across 1.x releases. If a need arises to modify the API in the future, it should happen with a bump in the major number, so, that will be 2.0.0 release, for example.

Happy scheduling!

Re-releasing with missing PR

Re-releasing to include needed PR that fixes unit tests.

Task ready time

• Introduces task ready time for QueuableTask such that if task has a future ready time, then it is skipped for consideration of resource assignments
• Fix autoscaler execution service to trigger scale up requests reliably. This also fixes the failing unit tests.

Task ready time

Merge pull request #164 from spodila/taskReadyTime

Task ready time

Introduce task ready time

Introduce a way for tasks to indicate when they are ready for consideration of resource assignments. A task with ready time in future is skipped from consideration for resource allocation.

Autoscaling reliability improvements

• Fix race condition on autoscaler by running autoscaling logic on scheduler thread
• Add spreading fitness calculator
• Handle inactive agent termination cycle independently from the active
• Add weighted average fitness calculator to more easily combine fitness calculator scores

Cleanup autoscaler logging statements

Merge pull request #159 from corindwyer/autoscaler-log-cleanup

Cleanup autoscaler log statements

Execute autoscaler synchronously on scheduler thread

• change autoscaler to be synchronously executed as part of the scheduling iteration while keeping the callback execution on a separate thread
• change shortfall analysis implementation to be synchronously executed as part of the autoscaler
• add withAutoscaleDisabledVmDurationInSecs for users that want to disable VMs for a fixed duration that is greater than the cooldown value
