[tftpserver] Merge pxe plugin into tftpserver

The `pxe` plugin was both antiquated in that no currently supported
distribution ships the `pxeos` command, and also duplicating some
behavior best served by the `tftpserver` plugin.

Move the relevant bits from `pxe` to `tftpserver`, then drop the `pxe`
plugin. Add some additional collections to `tftpserver` such as service
status collections.
