Upgrade to netty 4.1.56.Final and netty-tcnative 2.0.35.Final

[peter-janssen]

Problem

There are new netty releases and the classifier for AArch64 was changed from linux-aarch64 to linux-aarch_64. This results in dependency problems with other projects.

Solution

Upgrade to netty 4.1.56.Final and netty-tcnative 2.0.35.Final for security fixes and AArch64 dependency rename.

Thanks for the PR! To add a time expectation, we'll need to run some internal tests for this upgrade and that probably won't happen until after the holidays.

[bryce-anderson]

This is getting hung up on some changes in TLS behavior. See here for more details.

[bryce-anderson]

@peter-janssen, the patch to fix the ticket mentioned above should be in so we'll need to wait for another release before we can upgrade. Thanks for the PR, and once a release happens please feel free to submit another PR if we haven't already gotten around to it.
