This commit changes the logic around selecting jobs to run. Before this,
Boundary used a view "job_jobs_to_run" which was a collation of all jobs
that were not running and scheduled to run. When jobs were requested to
run, Boundary would look at this view, grab a certain amount of jobs and
insert them into the "job_run" table. Importantly, while the amount of
jobs to be scheduled at once defaulted to 1 in the scheduler package,
this was entirely overriden in the controller package to -1 (no limit,
run all jobs that the query would return).
With this commit, Boundary now looks at the "job" table directly for
jobs to run, regardless of job run status. This was done to improve DB
performance as the view (which queried all "job_run" rows) was causing
significant DB contention.
Additionally, the option to limit job runs is now removed since it was
already hardcoded to -1 and not user-configurable anyways.
Should the need arise to implement this limit again, this will have to
be done in a different way since the new query does not account for
running jobs and limiting the rows returned after jobs are already
running would yield a no-op (the new query inserts nothing into
"job_run" if any given job is already running).
Before this change, upon the completion of a job run, the scheduler
would update a job_run entry with the completed status as well as the
number of objects affected by the run. Additionally, we then had a
cleaner job whose scope was deleting these completed entries from
job_run.
This commit changes this design to drop the cleaner job the and rolls
its functionality directly into the scheduler. Now, when any given job
run is complete, the scheduler will automatically delete it from the
job_run table itself.
In addition, the completed status has been removed as a valid status as
it is not set anymore.
This change follows a decision that given the data in these job_run
entries is already being deleted by the cleaner job, updating its state
when a job completes just to have it deleted is not efficient.
Additionally, no use-case for this data was surfaced.
This adds retries as an attribute to JobStatus allowing a job to
indicate liveness to the scheduler when work has not progressed.
A job could use this and the statusThreshold passed into the Run method
to break work up into batches that would otherwise timeout if all the
work was attempted at once, for example a long running SQL delete
command.
The scheduler monitors running jobs to make sure they are not hung. If
the status of a running job does not change after a duration (the
interruptThreshold in the scheduler), the scheduler kills the job. This
change passes the scheduler's interruptThreshold to the job when it
calls Run() on the job.

* Updating the license from MPL to Business Source License
Going forward, this project will be licensed under the Business Source License v1.1. Please see our blog post for more details at https://hashi.co/bsl-blog, FAQ at www.hashicorp.com/licensing-faq, and details of the license at www.hashicorp.com/bsl.
* Update copyright file headers to BUS-1.1
* Rerun make gen
This will pick up the last of the license changes
* Revert "Rerun make gen"
This reverts commit dbe0968bffd92745d8663c6940debae098395a6b.
* Remove copywrite from generation script
The current version of copywrite is not sophisticated enough
to only apply the copywrite changes to certain subdirectories,
so to avoid accidentally relicensing our api and sdk modules,
we will stop running the copywrite script until such time
that it can do the right thing.
* License protobuf API as MPL
The protobuf API files are used to generate the SDK,
since we want the SDK to be MPL, the protobuf files
must also be MPL. This extends to all protobuf files
whose sources end up in the SDK directory, including:
- internal/proto/controller/api
- internal/proto/controller/custom_options
- internal/proto/plugin
It also includes the generated service directory in
internal/gen/controller/api/services, since they are
generated from the protobuf sources used for the SDK.
* Change website license file name
This makes the naming scheme consistent with the rest
of the repository.
* Add note on licensing to README
* Set copywrite license to BUSL
* Revert "Add note on licensing to README"
This reverts commit 4d865a91a7a4f11605f0dc4609355d7e3c3cfffe.

If a new job is started as the test successfully compeltes and begins
the scheduler shutdown process. The new job will deadlock waiting on
channel reads.
* Adds job repo
* Adds scheduler
* Adds plugin table which is a place holder for future expansion of the scheduler. Currently all jobs that are created are linked to the pi_system plugin which are jobs that are held in a local registeredJobs map populated at controller startup.
