Investigate Adding Support for t3 and m5 Instance-Types

[ferricoxide]

Problem Description:

AWS has released new instance types that might better align to some deployment-scopes

Expected Behavior:

Support t3 and m5 instance-types where possible

Actual Behavior:

Does not currently support t3 and m5 instance-types at all

(Optional) Fix recommendation:

Update template logic to allow for t3 and m5 instance-types

[ferricoxide]

Borrow the GenFive logic from the already-enabled cfn-jenkins project. Ensure:

• Presence of content in Conditions{} section.
• Presence content in Mappings{} section
• Presence of content in growpart directive's devices list in the UserData section

Note: Sonarqube doesn't currently have an AppVolume option: only need to account for root device.
