This command removes a server from being managed by Abra.

Depending on whether you used a 3rd party provider to create this server ("abra
server new"), you can also destroy the virtual server as well. Pass
"--server/-s" to tell Abra to try to delete this VPS.

Otherwise, Abra will remove the internal bookkeeping (~/.abra/servers/...) and
underlying client connection context. This server will then be lost in time,
like tears in rain.
