* comes from grafana/gel-app * remove transform plugin code * move __expr__ and -100 constants to expr pkg * set OrgID on request plugin context * use gtime for resample duration * in resample, rename "rule" to "window", use gtime for duration, parse duration before exec * remove gel entry from plugins-bundled/external.json which creates an empty array for plugins
