Separate AXE specs

[chao-xian]

What problem does this pull request solve?

Specs are like 7-11 minutes to run on local machines (even on snappy new MBPs it's ~5mins at best)

Taken the strategy of cutting out from running on local dev the AXE specs as we don't really touch these much.

This saves us between 20 to 60 seconds (whereas other strategies I tried would save about 10 seconds)

Things to consider when reviewing

• Ensure that you consider the wider context.
• Does it work when run on your machine?
• Is it clear what the code is doing?
• Do the commit messages explain why the changes were made?
• Are there all the unit tests needed?
• Do the end to end tests need updating before these changes will pass?
• Has all relevant documentation been updated?

It may take 5 minutes or so for the application to be fully deployed and working. If it still isn't ready
after 5 minutes, there may be something wrong with the ECS task. You will need to go to the integration AWS account
to debug, or otherwise ask an infrastructure person.
