Fix gauge display accuracy for "percent (0.0-1.0)"

Added underline to links in table

use pluginName consistently when upgrading plugins

fix: use datasource cache for backend datasources

The "Decimals" value was incorrectly applied to the metric value used to calculate the gauge display in addition to the text value (so a "Decimals" value of "1" turns "45.1%" into "50%" in the gauge display even though the label still correctly says "45.1%").

Fix anonymous usage stats for authentication types

[metrics]enabled = false should disable the /metrics endpoint.

Just wanted to reduce the amount of files/folders in root

[skip ci]

(prometheus) add annotation option to treat series value as timestamp 

add support for interpolate $__interval and  $__interval_ms in sql datasources

but we will still keep sending metrics to graphite
