Fix cleveldb, boltdb, rocksdb and badgerdb tests in CI

[p0mvn]

Background

We refactored benchmarks to test all databases in #465 . However, the CI is failing in bencher: https://dashboard.bencher.orijtech.com/benchmark/adc2a152a52245579ef92af91f4f0f74

In #468 we commented out all databases but memdb and goleveldb to allow bencher to pass.

From the initial investigation, the failure might be due to these additional databases requiring extra setup:
https://github.com/cosmos/iavl/blob/fe24be8d8d97a95c588554299eb045dea116a8a9/benchmarks/setup/INSTALL_ROOT.sh

However, more investigation is needed to determine the true source

Acceptance Criteria

• the root cause of bencher failures is found
• a PR with the fix is created
• bencher passes for all databases currently commented out in bench_test.go
• no time out observed

@faddat I think you did this work?

[faddat]

I did, but we are held up on a merge.

Here's what I'll do to resolve:

Close this PR:
#466

Finish implemeting this issue:
cosmos/cosmos-sdk#11688

Make this repository depend on that docker image.

Also, if there are no known usages of iavl outside of the cosmos-sdk, I want to recommend that we move this into cosmos/cosmos-sdk

Closing as we are migrating to cosmos-db and removed badger and bolt
