Cloudflared snapd package

Hello,

I am looking to use cloudflared on a raspberry pi running [Ubuntu Core](https://ubuntu.com/core). This is a very light weight operating system where the OS itself as well as applications are delivered as snap packages. It has a number of features that make it appealing for iot.

The cloudflared arm64 binary works and I have a tunnel up and running, but due to Ubuntu Core's design that most applications should be containerized in snaps, installing as a service is not available with the binary directly (many of the system directory are read only, even with sudo).

I am wondering if it's possible for Cloudflare to release a cloudflared snap package. It would make running cloudflared tunnels on any ubuntu system very quick and easy. An alternative I have considered is running cloudflared in a docker container (docker is supported on Ubuntu Core), but there is no arm64 release for the cloudflared docker container, [only amd64](https://hub.docker.com/r/cloudflare/cloudflared/tags).
