1. chore: Add future deprecation note for `component_(sent|received)_byt… …

   …es_total` metrics
   
   Vector originally published two component bytes metrics:
   
   - `component_sent_bytes_total` the number of serialized bytes successfully sent by sinks (before
     compression)
   - `component_received_bytes_total` the number of serialized bytes successfully received by sources
     (after decompression and filtering)
   
   These were intended to be used by users to understand the volume of data flowing in/out of sources
   and sinks. However, they were dependent on the exact serialization format such that the same event
   going into the `socket` source vs. `vector` source might be measured differently. To have
   a consistent metric we then added:
   
   - `component_sent_event_bytes_total` the number of "estimated JSON event" bytes successfully sent by a components
   - `component_received_event_bytes_total` the number of "estimated JSON event" bytes successfully received by a components
   
   This is a metric that is able to be compared between any two components. This removed a use-case of
   `component_(sent|received)_bytes_total`. The remaining use-case users seemed to use this metric for
   was as a proxy for network bytes, but what they really are interested in is the _actual_ network
   bytes. So we proposed two new metrics:
   
   - `component_sent_network_bytes_total` the total number of bytes sent out on the network by a
     component
   - `component_received_network_bytes_total` the total number of bytes received on the network by a
     component
   
   Once those metrics exist, it isn't clear what use-case remains for
   `component_(sent|received)_bytes_total` and so it would make sense to deprecate and remove them.
