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.
