Admin setting where the user can enable or disable hibernate for the EC2 launch in the UI

**Is your feature request related to a problem? Please describe.**
This is related with the [bug 59](https://github.com/aws/res/issues/59). In summary, the Hibernation option is enabled only for Windows and not for other operating systems that support it.

**Describe the solution you'd like**
The Launch New Virtual Desktop should has the hibernation option enable for all OS by default and not only for Windows, as it is in the AWS console when we create an EC2 instance. So, the admin can choose if the manchine can hibernate or not.

**Describe alternatives you've considered**
A general option where you can choose if all the deployable machines can be hibernated or not.

**Additional context**
For more technical details please review the issue 59:
https://github.com/aws/res/issues/59

Start by reviewing linked issue 59 and the Launch New Virtual Desktop flow described here, then trace how EC2 launch options are presented and passed for supported operating systems. Done means an administrator can enable or disable hibernation for a virtual desktop launch, with hibernation available by default for every supported OS.
