Felix version 2.1.0

- Port dataplane driver to Golang and move in-process (#1202).
  This has a number of benefits and allowed for a number of
  bugfixes and enhancements to be worked in:

  - Improve dataplane programming performance and decrease
    occupancy by having only one process instead of two.
    It also simplifies the codebase substantially.
  - Simplify deployment (now only one binary needed).
  - Use netlink directly for critical-path route programming
    operations.
  - Move to a synchronization model for route programming.
    Allows for monitoring and restoring routes if they are
    removed.  Allows for clean up of routes that relate to
    orphaned endpoints.
  - Ensure IPIP tunnel device configuration is maintained;
    replace it if it is accidentally removed.
  - Retry iptables/ipset updates in more failure cases to work
    around transient failures of those commands.
  - Switch to a synchronisation model for iptables.  Avoid
    reprogramming rules that haven't changed.  This improves
    performance.
  - Label our iptables rules with a hash to allow rules to be
    identified.  Allows for simpler sync and cleanup.
  - Limit OpenStack special-case rules to deployments with "tap"
    devices (#1020).

- Add support for host endpoint policies that bypass the conntrack
  table.  Useful for high connection throughput workloads such as
  memcacheDB. (#1284)
- Fix that setting LogFilePath doesn't prevent early logging (#803)
- Fix log spam when adding tunl0 device (#1008)
- Retry ipset commands to deal with transient failures (#1181)
- Document deb/RPM release process (#1237)
- Rev libcalico-go to v1.1.3, includes a number of fixes (#1364).
