* Config: Version Management
* Engine: Improve visibility of TestConfigAllJsonResponse failures
* Config: Update cmd/config to allow upgrades
* Config: Add Version2 to rename GDAX
* Config: Restructure versioning to share types
This restructure allows us to share types between versions, avoids
needing to import the versions, and puts the test fixtures in same
package.
It's a win on all fronts
* Config: Fix SetNTPCheck using log
Called from engine before logger is inited, and also just wrong to use
log to communicate with user
* Config: Improve TestMigrateConfig
* Config: Drop requirement for versions to be registered in sequence
Checking the versions at Deploy is much saner.
* Config: Fix file encrypted but flag not set
* Config: Add -edit and encryption upgrade to cmd/config
This simplifies the handling for encryption prompts by moving it to a
field on config, allowing us to simplify all the places were were
passing around config
Also moves password entry to being secure (echo-off)
* Tests: Fix inconsistent should/must assertions
