- Changes behaviour of details param handling via global setting: - listVirtualMachines API: when the details param is not provided, it returns whether stats are returned controlled by a new global setting `list.vm.default.details.stats` - listVirtualMachinesMetrics API: when the details param is not provided, it uses `all` details including `stats` - Users who are affected slow performance of the listVirtualMachines API response time can set `list.vm.default.details.stats` to `false` - Remove ConfigKey vm.stats.increment.metrics.in.memory which was renamed to `vm.stats.increment.metrics` in #5984 and also remove unused/unnecessary global settings via upgrade path - Changes default value of VM stats accumulation setting `vm.stats.increment.metrics` to false until a better solution emerges. Since #5984, this is true and during the execution of listVM APIs the stats are clubbed/calculated which can immensely slow down list VM API calls. Any costly operations such as summing of stats shouldn't be done during the course of a synchronous API, such as the list VM API. - Fix UI that uses listVirtualMachinesMetrics to not call `stats` detail when in list view without metrics selected.
