v2.3.1

fix: incorrect attribute types in graph overlays (docs vs what api actually returns)

v2.3.0

fix: func signature to match go-retryablehttp update
upd: dependency go-retryablehttp, lock to v0.5.2 to prevent future breaking patch features

upd: switch from tracking master to versions for retryablehttp and circonusllhist now that both repositories are doing releases

fix: worksheet.graphs is a required attribute. worksheet.smart_queries is an optional attribute.

upd: remove go.{mod,dep} as cgm being v2 causes more issues than it solves at this point. will re-add after go mod becomes more common and adding v2 to all internal import statements won't cause additional issues.

fix: if submission url host is 'api.circonus.com' do not use private CA in TLSConfig

fix: do not reset counter|gauge|text funcs after each snapshot (only on explicit call to Reset)
upd: dashboards - optional widget attributes - which are structs - should be pointers for correct omission in json sent to api
fix: dashboards - remove omitempty from required attributes
fix: graphs - remove omitempty from required attributes
fix: worksheets - correct attribute name, remove omitempty from required attributes
fix: handle case where a broker has no external host or ip set

gauges as interface{}
- change: GeTestGauge(string) (string,error) -> GeTestGauge(string) (interface{},error)
- add: AddGauge(string, interface{}) to add a delta value to an existing gauge
