build(deps): bump chrono from 0.4.19 to 0.4.20

[teor2345]

Motivation

chrono has fixed rust security advisory: https://rustsec.org/advisories/RUSTSEC-2020-0159

It has also fixed some panic bugs.

Solution

• Bump chrono to 0.4.20

Related build / security fixes:

• Drop old time crate dependency from chrono

Related clippy fixes:

• Fix clippy::assign_op_pattern
• Update deprecated constant names

Review

Zebra isn't actually vulnerable to this security issue in our direct use of chrono, but tracing might be, so we should get this merged before the next release.

Reviewer Checklist

• [ ] Existing tests pass

We're seeing panics in Zebra, so this is now a high priority.
