* Node should advertise its pod CIDR to external BGP peers only if
--advertise-node-pod-cidr is set to true (defaults to true).
This is to enable a case where pod's remain non-routable from out of the
cluster but service VIP's can be routable from out side the cluster.

* fix unit test

* address review comments

* split routing controllers to smaller modules by function

* review comments

* update gobgp to d31262de7d91c81ff979b39950d2d859666dfa3f for graceful restart fixes

* fix addExportPolicies test due to new gobgp version

* minimize sync() done by the controllers

* deprecate --config-sync-period

* review comments

* code restructuring as per typical golang projects

* fix link in docs

Fixes #385

* vendor changes from dep init

* add Gopkg.lock and Gopkg.toml

* delete glide.lock and glide.yaml

* build gobgp from vendor

* Added option BUILD_IN_DOCKER to build binarys in a docker container

* removed unnecessary deps

* locked docker image version for buildin

* delete package app/watchers since we're now using shared informers

* used shared informers for events and listing resources

* install moq in travis test script

* network services controller testing via moq and ginkgo

* add network_services_test case for LoadBalancer w/o IPs

* no-change-commit: glide.yaml: pin ginkgo and gomega versions, update only these in vendor/

* golint fixes

* fixes from @andrewsykim review

* group std imports

* update command line options documentation

* add test for command line help doc

* Fixed the /var/run/docker.sock permissions in the DSR example

* Set both mounts to read-only

annotation is set

* fix --advertise-loadbalancer-ips for LoadBalancer w/o IPs

* fix network_services_controller.go also for no lb IPs

* [jjo] support advertising status.loadBalancer.ingress IPs via flag

* add `--advertise-loadbalancer-ip` flag, which will make Service's
  Ingress IP(s)set by the LoadBalancer to:
- be locally added to nodes' `kube-dummy-if` network interface
- be advertised to BGP peers

* support "kube-router.io/service.skiplbips=true" per Service
  annotation to selectively skip above

* refactor several functions with dupped code to streamline logic as:
  - `getIpsToAdvertise()` which calls ->
    - `getClusterIPs()`
    - `getExternalIPs()`
    - `getLoadBalancerIPs()`
    and contains nodeHasEndpoints logic, returns:
      (ipsToAdvertise, ipsToUnAdvertise)
  - advertiseIPs() which is essentially previous advertiseClusterIPs()
    (which was previously used to advertise _any_ IP actually, ie misnamed),
    with logic to un/advertise based on both passed arguments:
      (ipsToAdvertise, ipsToUnAdvertise)

* fix some leftovers from uselbips -> skiplbips annotation change

* Test_addExportPolicies

* default export policy should always be REJECT

withdraw ClusterIP bgp route for externalTrafficPolicy=Local when there are no local endpoints (#347)

* unadvertising service ips for services without endpoints

Couple changes to improve local development, building, etc.

* use ADD instead of COPY to force cache invalidation
* rearrange to cache more expensive network downloads (apk, etc),
  ADDing locally built binaries at last
