Update Bacalhau to use RPC interface (instead of shell commands)

[walkah]

Bacalhau > v1.4 deprecated the commands that we use to run jobs: https://docs.bacalhau.org/references/cli-reference/command-migration

Also, using the CLI to run jobs requires bacalhau installed locally (which means bundling bacalhau inside our RP docker container).

bacalhau has a lib to do this. things became more stable with this api.

We should consider removing the Bacalhau executor integration out of pkg/data into pkg/executor/bacalhau alongside the executor. At the time of writing, we also use Bacalhau for it's embedded IPFS, so some parts of the code may be more appropriate in directory or storage package.
