Error handling for menu API requests

[fago]

Currently we do that:

https://github.com/drunomics/nuxtjs-drupal-ce/blob/1.x/lib/plugin.mjs#L135:

      } catch (error) {
        // Ignore the error and only log it, so the site stays functional.
        // eslint-disable-next-line no-console
        console.log(error)

Planned solution:

• Add general axios error handler to drupal-ce axios instance
• Have general axios error handler be used for menu API requests - thus we stop ignoring the error
• The default should throw the error and handle the typical cases like getPage (response error, no response error, other error)
• We need make sure a menu-API errors are giving enough context and tell us which API request is broken
