Allow to specify node_connection_info for redis sentinel

[ederuiter]

This allows you to select a different database/username/password for the connections to the underlying redis servers.

Closes #367

Build failures seem unrelated to these changes; they all fail building a dependency

error: could not compile `value-bag` (lib) due to 3 previous errors

[bikeshedder]

Yes, those errors are completely unrelated.

It's quite a bummer that the dependencies keep breaking the MSRV checks of the deadpool crates. 😞

btw. I'd just call that field node_connection_info to keep it in line with redis-rs:

• https://github.com/redis-rs/redis-rs/blob/2839854daa1833b9edbdcd29eac1af50b61bd85a/redis/src/sentinel.rs#L728
• https://github.com/redis-rs/redis-rs/blob/2839854daa1833b9edbdcd29eac1af50b61bd85a/redis/src/sentinel.rs#L738

Apart from that I don't see anything wrong with the PR. It's nitty picky, I know. I just don't think adding the sentinel_ prefix adds anything here except for extra verboseness when using the now public API.

Makes sense; I amended my commit with the changes

@bikeshedder would it be possible to release a new version of deadpool-redis?

[bikeshedder]

I'm currently hesitant releasing a version with #357 being merged which adds a feature that I'm going to rework as part of #226. I could either revert #357 and make a release that only adds this PR or release a version that also includes a change that is going to be reverted/reworked.

I'm thinking of going the middle ground. Reworking #357 so it just adds the timeout config which can be kept even when PubSub support lands in deadpool-redis. 😅

I just need a moment to make those changes. I'll release a new version of deadpool-redis asap.
