Improve failed plugin upload messaging

Is it possible to be more specific with the error message when a plugin fails to upload. For example, if the framework installed is lower than that required by the plugin, you just get the standard message:
Plugin upload failed
Installation of plugins failed, Installation of plugin '[name]' via adapt-cli failed

It would be helpful if the message indicated the reason why.

Strongly agree. Perhaps in the short term we can at least adjust the messaging to list some things to check such as:

"Plugin upload failed, please check that the version of the plugin is compatible with the installed framework (fw)"

where fw is the installed framework version
