Em Sharnoff 1fe23fe8d2 compute/lfc: Add chunk size to neon_lfc_stats (#11100) 
This PR adds a new key to neon.neon_lfc_stats —
'file_cache_chunk_size_pages'. It just returns the value of
BLOCKS_PER_CHUNK from the LFC implementation.

The new value should (eventually) allow changing the chunk size without
breaking any places that rely on LFC stats values measured in number of
chunks.

See neondatabase/cloud#25170 for more.

Compute Configuration

These files are the configuration files for various other pieces of software that will be running in the compute alongside Postgres.

Adding a sql_exporter Metric

We use sql_exporter to export various metrics from Postgres. In order to add a metric, you will need to create two files: a libsonnet and a sql file. You will then import the libsonnet file in one of the collector files, and the sql file will be imported in the libsonnet file.

In the event your statistic is an LSN, you may want to cast it to a float8 because Prometheus only supports floats. It's probably fine because float8 can store integers from -2^53 to +2^53 exactly.
