make error type compatible with `anyhow::Error`

[databasedav]

this provides more ergonomic error handling with ?

anyhow::Error

i currently get something like this from an aerospike_client.get(...)?

IIRC that's the fundamental issue with chain_error and why it was abandoned. We are going to move to thiserror to address this issue. I'm a bit tied elsewhere right now so I invite pull requests, but I'll do it myself in a week or two if no one volunteers.

@khaf i can do the port to thiserror, is it ok if i target the async branch?

[khaf]

Yes, please do it. I'll review and merge it as soon as I can.

@khaf getting these testing outputs (with warning omitted) on the async branch

this is all hitting a ce-6.3.0.2 docker container

i don't see any of these errors in the ci, but i also don't see these running here https://ci.appveyor.com/project/aerospike/aerospike-client-rust

any idea what's causing the invalid buffer size errors? just wanted to make the tests pass locally before replacing the errors

[khaf]

Yes I have fixed all of these with that last release, and will push the changes today if I get the time to fix a couple of tests due to server v6 default config changes.

[khaf]

Pushed.
