Title: Allow AWS EBS volume size and type to be set via config.

When using an EBS only instance type (like a t2), ebs_size and ebs_type allow you to define the EBS volume generated.

`ebs_type` can be 'standard' (default), which is a magnetic disk; or 'gp2' which is an SSD.
`ebs_size` is an integer measured in gigabytes. If no value is provided, the default is 8GB.

An example config would now look like:
```
lpa_dev:
image_id: ami-9656a1e1
provisioning_ssh_key: ../config/default.pem
provisioning_ssh_key_name: default
instance_type: t2.medium
ebs_size: 20
ebs_type: gp2
security_groups:
- MoJ-to-SSH
- MoJ-to-Web
provisioning_user: ubuntu
region_name: eu-west-1
driver: aws
```
