When using the json output of the cli (`-format=json`), a successful
call to the controller API would place the HTTP status code in the JSON
as `status_code`. However, if there was an error from the API the status
code would be placed in the JSON as `status`. In order to be consistent,
this adds a `status_code` field to the error response case. For
backwards compatibility it still populates `status` in the error case.
This inconsistency was missed partially due to a bug in the CLI tests.
The assertion on status code was not valid and would always be
successful. Thus this also fixes the assertions and tests.
This ensures that checks for features should work, and bails early if
that is not the case, since if this fails the binary is essentially
broken. This also simplifies code that performs these checks, ie instead
of:
binaryVersion, err := version.GetReleaseVersion()
if err != nil {
// handle error? panic?
}
if version.SupportsFeature(binaryVersion, version.FeatureA) {
// code for FeatureA
} else {
// without FeatureA
}
Implementations can do:
if version.SupportsFeature(version.Binary, version.FeatureA) {
// code for FeatureA
} else {
// without FeatureA
}
