chore(blooms): Add jsonnet lib for bloom filter components

[chaudum]

What this PR does / why we need it:

This PR adds the jsonnet lib for deploying bloom filter components (bloom-compactor for the write path, bloom-gateway for the read path) again.

Special notes for your reviewer:

This lib has been originally added with #11397, #11530, #11741 and removed with #11984.

⚠️ 🚧 ⚠️ Bloom filters are still an experimental feature. Do not enable the flag $._config.use_bloom_filters unless you know what you're doing and/or actively developing the feature.
