refactored BGP configs, kubevip pkg and more.

Browse Source 
* Moved functions from mod pkg vip to pkg utils
* remove the dependency of the kubevip config pkg on the bgp pkg
* introduce BGPConfig and BGPPeer to kubevip package and migrate label from node labeler
* Use the new BGPConfig and BGPPeer type of the kubevip pkg
* Removed utils functions from vip pkg and refactor to call utils instead
* migrate from pkg vip to utils for generic IP funcs
* migrate common annotations and labels into a central place + support for hostnames
* if any change happens we want to reconcile it here
* fix e2e tests which relied also on the vip package instead of utils
* Better debug logging
* Added info if it is egress
* added missing condition to dhcp specific actions
* Disable the service before cancelling the context
* lets try auto,auto instead of /32 and nothing
* Let's reset svcCtx to be nil to ensure a new context when the previous was garbage collected
* Added a space for project wide constants
