exchanges: Add dynamic function checking to determine exchange functionality

[shazbert]

PR Description

• Adds AutomaticPreFlightCheck function to determine functionality support between protocols and asset types.
• This is a POC for eligibility testing. This is backwards compatible and constricted to gateio for initial documentation output.
• This attempts to standardise what is available across exchange implementations between functionality for a quicker decision on what endpoints to use and dynamically scale up and down depending on actual support. Specifically started with trading endpoints to keep things simple.
