PushMetricExporter when using console, properties missing

[marcalff]

When a PushMetricExporter uses the console, the type used is:

                "console": {
                    "$ref": "common.json#/$defs/ConsoleExporter"

Reusing ConsoleExporter means there are no temporality_preference and default_histogram_aggregation properties.

Should PushMetricExporter use a new type ConsoleMetricExporter instead, which adds these properties ?

This is blocking RC release 1.0.0

See #161

"Standard output" Metrics Exporter MUST provide configuration to set the MetricReader output temporality as a function of instrument kind. This option MAY be named temporality, and MUST set temporality to Cumulative for all instrument kinds by default.

"Standard output" Metrics Exporter MAY provide configuration to set the MetricReader default aggregation as a function of instrument kind. This option MAY be named default_aggregation, and MUST use the default aggregation by default.

Console property for temporality_preference is required, so this is a breaking change from version 1.0.0-rc1
