- Closes #150, #394. - Introduces `AttachmentConfiguration` type so that we can add key-value options to `--network` in the future. - Eliminates redundant `ContainersService.Item` type. - Since we now ensure at ContainersService that hostnames will not conflict, the network helper IP allocator now simply provides the existing IP if for an allocation on an existing hostname, which should handle (in an eventually consistent way) the case where a container fails to deallocate an IP on shutdown.
