Release 0.5.0 · crate/cratedb-prometheus-adapter

What's Changed

Accept invoking the program without default configuration file config.yml
In this case, the program will fall back to the builtin defaults, essentially
connecting to localhost:5432 with username crate.
Add query timeouts using context cancellation. The corresponding
configuration settings are read_timeout and write_timeout.
Use a different connection pool for read vs. write operations.
The corresponding settings to configure the maximum pool sizes
are read_pool_size_max and write_pool_size_max.
Accept invocation without default configuration file config.yml.
Add command line option -config.make to print a blueprint configuration
file to stdout.
Use a DSN-style connection string for talking to pgx5.
Add program version to startup log message.

Add support for Go 1.20 and 1.21, drop support for previous releases
Update dependency packages across the board to their latest or minor patch releases
Update Prometheus libraries (client: 1.18, server: 2.48)
Update Protocol Buffers libraries (google.golang.org/protobuf 1.31)
Update to pgx5 library

This release removes the default value for the -config.file command line
option, which was config.yml. When the option is omitted, the service
will use the built-in settings, connecting to CrateDB on localhost:5432.
