internal/telemetry/export/ocagent: attach timestamps to metrics

This change attaches start timestamps to timeseries and end
timestamps to the points in each timeseries. Int64Data,
Float64Data, HistogramInt64Data, and HistogramFloat64Data
have also had an EndTime field added to keep track of the last
time the metric was updated.

What works:
* Start and end timestamps will now be attached to timeseries.

What does not work yet:
* MetricDescriptors will not have a unit attached.
* No labels will be attached to timeseries.
* Distributions will not have SumOfSquaredDeviation attached.

Updates golang/go#33819

Go Tools

This subrepository holds the source for various packages and tools that support the Go programming language.

Some of the tools, godoc and vet for example, are included in binary Go distributions.

Others, including the Go guru and the test coverage tool, can be fetched with go get.

Packages include a type-checker for Go and an implementation of the Static Single Assignment form (SSA) representation for Go programs.

Download/Install

The easiest way to install is to run go get -u golang.org/x/tools/.... You can also manually git clone the repository to $GOPATH/src/golang.org/x/tools.
