`fcli * rest call`: Issues with input and record transformations

[rsenden]

The fcli * rest call commands are expected to do input and record transformation by default, allowing this behavior to be disabled through the --no-transform option. However, there are some issues with this approach:

• Users may expect to see the same record transformations as on other fcli commands.
  • For example, when calling fcli ssc rest call /api/v1/projectVersions, users may expect the project property to be renamed to application just like in the fcli ssc appversion list command
  • However, since most record transformations are defined at command-level rather than product level, such transformations will not take place and thus the rest call command above will output the project property as-is
• The --no-transform option currently doesn't have any effect, as currently there is no way to 'override' the default input transformations performed by the product helper mixins

We can't really fix the first issue in a nice way (we'd need to move all command/entity-specific record transformations to the central product helper). We should however fix the second issue, as users may be interested in seeing the raw response data to access for example the SSC count, responseCode and links properties.

Apart from fixing the above, we may want to allow for extracting arbitrary data from the response using an SpEL expression (allowing to specify a property path, using collection selection/projection, ...).
