[PATCH proxmox v3 1/2] http: move http proxy schema from PBS to crate's api types

[Christian Ebner <c.ebner@proxmox.com>]

The http proxy schema is used in combination with the ProxyConfig for
verification, the latter being part of the crate already.

Move also the schema to the crate and guard it behind a api-types
feature to allow for conditional compilation thereof.

This will easy refactoring the node config in PBS.
