Bug fixes

Changes expected to improve the state of the world and are unlikely to have negative effects

• dynatrace: Fixed a division by zero bug in the Dynatrace sampling controller that occurred when total_wanted was less than top_k_size. The calculation was refactored to avoid the intermediate division that could result in zero.

• release: Container (Ubuntu/distroless) updates, and fixed permissions for distroless config directory.

• tls: Fixed an issue with incorrectly cached connection properties on TLS connections. If TLS connection data was queried before it was available, an empty value was being incorrectly cached, preventing later calls from getting the correct value. This could be triggered with a tcp_proxy access log configured to emit a log upon connection establishment if the log contains fields of the the TLS peer certificate. Then a later use of the data, such as the network RBAC filter validating a peer certificate SAN, may incorrectly fail due to the empty cached value.
