Error handling method for several remote providers and normalize the error messages.

[ultraprinse]

This issue is related to the issue which have been merged.
The root cause of the issue was that we don't have any error handlers to handle errors that we get from remote providers. The PR resolved the errors that happens from Gitlab.

But the error type from each remote providers, they are not the same.

So things which need to be improved;

• Have proper error handler for all remote providers.
• Normalize and remapping error message to something which is more understandable for users.
