internal/coordinator/pool: add ledger

This change adds a ledger to the coordinator pool package. The ledger
is used to store a record of EC2 instance types created and their
attributes. It also keeps a record of resource usage for EC2 instances
in order to ensure that we do not exceed the resource limits for the account.

Updates golang/go#36841
