2020-03-31Switching over to soft feature flag (#8545)Andrew Moss
Preparing for the cloud release. This changes how we handle the feature flag so that it no longer requires installer switches and can be set from the config file. This still requires internal access to use and is not ready for public access yet.
2020-03-31Improve the behavior of claiming (#8516)Andrew Moss
The default cloud url has been updated to app.netdata.cloud ready for the release. The claiming process now checks the current user executing claiming and refuses to perform the claim for the wrong user. If the current UID is 0 then claiming proceeds but the file ownership is adjusted to be the correct netdata user. The default expected user is `netdata` unless the script can identify the user from the current configuration. After the claiming script is executed the CLI is used to reload the claiming state.
