Update to elastic/beats@d95f6bab8554

- Update to Go 1.16.4
- Adapt to elastic/beats#25696
- golint fixes
- Add gotestsum to go.mod
- tests: chown go.sum files

go mod download will download all modules, even
if they are not used (e.g. dependencies of parts
of beats that are not dependencies of apm-server).
As such the command may need to update go.sum,
so make sure it is owned by the running user.

+=== data_stream
+
+The data_stream fields take part in defining the new data stream naming scheme.
+In the new data stream naming scheme the value of the data stream fields combine to the name of the actual data stream in the following manner: `{data_stream.type}-{data_stream.dataset}-{data_stream.namespace}`. This means the fields can only contain characters that are valid as part of names of data streams. More details about this can be found in this https://www.elastic.co/blog/an-introduction-to-the-elastic-data-stream-naming-scheme[blog post].
+An Elasticsearch data stream consists of one or more backing indices, and a data stream name forms part of the backing indices names. Due to this convention, data streams must also follow index naming restrictions. For example, data stream names cannot include `\`, `/`, `*`, `?`, `"`, `<`, `>`, `|`, ` ` (space character), `,`, or `#`. Please see the Elasticsearch reference for additional https://www.elastic.co/guide/en/elasticsearch/reference/current/indices-create-index.html#indices-create-api-path-params[restrictions].
+
+
+*`data_stream.dataset`*::
++
+--
+The field can contain anything that makes sense to signify the source of the data.
+Examples include `nginx.access`, `prometheus`, `endpoint` etc. For data streams that otherwise fit, but that do not have dataset set we use the value "generic" for the dataset value. `event.dataset` should have the same value as `data_stream.dataset`.
+Beyond the Elasticsearch data stream naming criteria noted above, the `dataset` value has additional restrictions:
+  * Must not contain `-`
+  * No longer than 100 characters
+
+type: constant_keyword
+
+example: nginx.access
+
+--
+
+*`data_stream.namespace`*::
++
+--
+A user defined namespace. Namespaces are useful to allow grouping of data.
+Many users already organize their indices this way, and the data stream naming scheme now provides this best practice as a default. Many users will populate this field with `default`. If no value is used, it falls back to `default`.
+Beyond the Elasticsearch index naming criteria noted above, `namespace` value has the additional restrictions:
+  * Must not contain `-`
+  * No longer than 100 characters

+
+*`data_stream.type`*::
