* Add Run() helper for external providers

This interface is similar to the common.Provider interface, but lacks
the AsParams() function. Decoupling the external provider interface from
the internal provider interface allows us to account for any
particularities there may appear between them.

The execution package is a common package that can be used by external
providers to load environment variables and stdin, in a coherent struct
that can be consumed by the various commands that need to execute as
part of the provider.

The params package should not depend on config. The params packages
should be consumable by external applications that wish to interact with
garm, and it makes no sense to pull in the config package just for some
constants. As such, the following changes have been made:
* Moved some types from config to params
* Moved defaults in a new leaf package called appdefaults

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.

Add a grace period for idle runners of 5 minutes. A new idle runner will
not be taken into consideration for scale-down unless it's older than 5
minutes. This should prevent situations where the scaleDown() routine
that runs every minute will evaluate candidates for reaping and
erroneously count the new one as well. The in_progress hooks that
transitiones an idle runner to "active" may arive a long while after the
"queued" hook has spun up a runner.

The TLS listener was not being set up correctly. The TLSConfig was changed
to include only cert and key. The cert now needs to be a full chain bundle
including intermediary CA certificates. The ca_cert config option was removed.

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.

On some providers the default character set used by shortid may lead to
errors when creating runners, due to the fact that underscores are not
allowed in their names.
