Instance Type is not used and therefore defaults to t2.micro

[itsbmr]

Describe the bug

starting from failover.yaml entering a valid instance type such as m5.large the stack will fail

Expected behavior

It should take the instance type entered in the paramers and pass it to application.yaml

Current behavior

The stack is failing with an invalid instance type error. When you analyse the events you can see it is trying to use t2.micro which is the default in application.yaml

Workaround is to amend the application.yaml so that the default instance type is the one you want.
