Please allow "classic" confinement for the "sccache" snap

I uploaded a snap for sccache, a ccache-like software capable of storing its cache in the cloud. It, being a developer tool, a wrapper for compilers, can’t be strictly confined at the moment.

Please allow classic confinement for it.

It makes sense that classic is needed for this snap. I agree that at this time this is the only option. I have vetted the publisher. Granting. This is now live.
