Bump dependency versions

[DCardenasAmp]

Delayed this PR until envoy got updated. This PR updates the following dependencies:

• Clojure (1.10.1 -> 1.11.1)
• tools.cli (1.0.194 -> 1.0.206)
• tools.logging (0.5.0 -> 1.2.4)
• data.xml (0.0.8 -> 0.2.0-alpha6) to match the version used by cloverage
• envoy (0.3.3 -> 1.0.1)
• com.stuartsierra.component (1.0.0 -> 1.1.0)
• lein-codox (0.10.7 -> 0.10.8)
• lein-cloverage (1.1.2 -> 1.2.4)

While I was at it, I also upgraded cljstyle to 0.15.0 and made linting changes.

Tested this with just the CI tools.
