  1. Report output plugin statistics in pg_stat_replication_slots 

    As of now pg_stat_replication_slots reports statistics about the reorder
buffer, but it does not report output plugin statistics like the amount of data
filtered by the output plugin, amount of data sent downstream or the
number of transactions sent downstream. This statistics is useful when
investigating issues related to a slow downstream.

This commit adds following fields to pg_stat_replication_slots
- plugin_filtered_bytes is the amount of changes filtered out by the
  output plugin
- plugin_sent_txns is the amount of transactions sent downstream by the
  output plugin
- plugin_sent_bytes is the amount of data sent downstream by the output
  plugin.

The prefix "plugin_" indicates that these counters are related to and
maintained by the output plugin. An output plugin may choose not to
initialize LogicalDecodingContext::stats, which holds these counters, in
which case the above columns will be reported as NULL.

Filtered bytes are reported next to total_bytes to keep these two
closely related fields together.

Additionally report name of the output plugin in the view for an easy
reference.
