when setting a subscription key from the cli, use http(s)_proxy as tunnel if
evironment variable is set.
Note: adds hyper-proxy crate and bumps bumps base64 to v0.13, due to a
dependency of hyper-proxy.
Signed-off-by: Dylan Whyte <d.whyte@proxmox.com>

Changes v1 -> v2:
- Accept proxy as optional argument to post function
- Create proxy client in separate function
- Read proxy env variable in register_subscription(..)
- Include fixme note to change to config file later
- Code cleanup
Notes:
v2:
- This is currently just for the command line. To do this over the API,
it would be better to have a config file.
- I am also leaving the apt configuration until the plan for this config
file is confirmed.
v1:
* required packages can be found in nasi/iso/packages/hyper-proxy
Note that proxy authorization/authentication is not implemented yet.
hyper-proxy implements it using the 'headers' crate, which we do
not have as a direct dependency. I figured i'd leave it for a
follow up patch, just in case we decide not to use hyper-proxy afterall.
