When VERSION is set to a development snapshot (micro >= 50), or a release candidate (micro >= 90) we have an off-by-1 in determining deprecation and deletion thresholds for versioned machine types. In such cases we need to use the next major/minor version in threshold checks. This adapts the deprecation macros to do "next version" prediction when seeing a dev/rc version number. This ensures users of release candidates get an accurate view of machines that will be deprecated/deleted in the final release. This requires hardcoding our current release policy of 3 releases per year, with a major bump at the start of each year, and that dev/rc versions have micro >= 50. Signed-off-by: Daniel P.
