Adds a simple database watcher. At this point it's just one process, but
the plan is to allow different implementations that inform the local running
workers of changes that have occured on entities of interest in the database.

This change removes a check that denies the creation of a pool
if the new pool has the same image and flavor set on the same
provider. The reasoning for that check was that if you need to
create another pool with identical settings to an existing one,
you might as well scale up the min-idle-runners on the old one.
This was done when runner groups were not yet added. This in
turn has forced users to alias images with new names in their
provider, leading to terrible UX. In the end, being too
opinionated in this case has caused more harm than good.
Fixes#245

We'll use GithubEntityType throughout the codebase to determine the
type of operation that is about to take place, so this won't belimited
to determining only pool type. We'll also use this to dedupe the label
scope as well.

This change adds the ability to specify the pool balancing strategy to
use when processing queued jobs. Before this change, GARM would round-robin
through all pools that matched the set of tags requested by queued jobs.
When round-robin (default) is used for an entity (repo, org or enterprise)
and you have 2 pools defined for that entity with a common set of tags that
match 10 jobs (for example), then those jobs would trigger the creation of
a new runner in each of the two pools in turn. Job 1 would go to pool 1,
job 2 would go to pool 2, job 3 to pool 1, job 4 to pool 2 and so on.
When "stack" is used, those same 10 jobs would trigger the creation of a
new runner in the pool with the highest priority, every time.
In both cases, if a pool is full, the next one would be tried automatically.
For the stack case, this would mean that if pool 2 had a priority of 10 and
pool 1 would have a priority of 5, pool 2 would be saturated first, then
pool 1.

* Updates the garm-provider-common and go-github packages.
* Update sqlToParamsInstance to return an error when unmarshaling
This change is needed to pull in the new Seal/Unseal functions in common.

This change renames the module from "garm" to "github.com/cloudbase/garm".
This will make it easier to consume public functions defined in garm, by
external applications, without having to resort to replace.

Extra specs is an opaque valid JSON that can be set on a pool and which
will be passed along to the provider as part of instance bootstrap params.
This field is meant to allow operators to send extra configuration values
to external or built-in providers. The extra specs is not interpreted or
useful in any way to garm itself, but it may be useful to the provider
which interacts with the IaaS.
The extra specs are not meant to be used for secrets. Adding sensitive
information to this field is highly discouraged. This field is meant as a
means to add fine tuning knobs to the providers, on a per pool basis.
