The handler does not need to close the request body. The http server will do that for you.

Nice, never knew that.

Feel good about the overall approach. |

This adds ability to add and remove reservations for subnet allocations. A subnet is reserved with the host IP (PublicIP). flannel will then use this subnet for a host requesting a subnet. Reservations are denoted in etcd as subnets with no expiration (TTL is zero). When a reserved subnet is allocated, it's TTL continues to be not set. If a reservation is removed, the TTL is set to the usual 24 hours. Also adds corresponding client/server APIs for reservation management. Fixes flannel-io#280

Do we have an e2e test or integration test yet? The code LGTM. |
|
We don't have e2e tests. That's on a todo list and it's non-trivial task as it requires setting up etcd and multiple containers or VMs for flannel daemons. |

This adds ability to add and remove reservations
for subnet allocations. A subnet is reserved with
the host IP (PublicIP). flannel will then use this
subnet for a host requesting a subnet.
Reservations are denoted in etcd as subnets with no
expiration (TTL is zero). When a reserved subnet is
allocated, it's TTL continues to be not set. If a
reservation is removed, the TTL is set to the usual
24 hours.
Also adds corresponding client/server APIs for
reservation management.
Fixes #280
