* Update pebble db to latest format by default
If the pebble database format is not explicitly set in the config, then set it to the latest format version by default. This will ensure that the database format is sufficiently up-to-date to be compatible with a major version upgrade of pebble.
* chore: stop using go-homedir
The `github.com/mitchellh/go-homedir` repo is archived, no longer needed, and no longer maintained.
- `homedir.Dir` is replaced by the stdlib `os.UserHomeDir`
- `homedir.Expand` is replaced by fsutil.ExpandHome` in the `github.com/ipfs/kubo/misc/fsutil` package.
Additional functionality, such as `DirWritable` and `FileExists` was moved into or included in the `github.com/ipfs/kubo/misc/fsutil` package.
* include pebble as built-in plugin
Pebble provides a high-performance alternative to leveldb as the datastore, and will serve as a replacement for badger1.
There are a number of tuning parameters available for tuning pebble's performance to your specific needs. Default values are used for any that are not configured or are set to the parameter's zero-value.
