This removes use of gnutls and the TLS implementation, which is no longer needed (task synchronization is handled via Taskchampion, which uses `reqwest`, which handles TLS via other Rust dependencies). This incidentally removes the following config options: * `debug.tls` * `taskd.ca` * `taskd.certificate` * `taskd.ciphers` * `taskd.credentials` * `taskd.key` * `taskd.server` * `taskd.trust`
Shell environment variables that affect how and what tests are executed: TASKW_SKIP -> Causes any test that needs Taskwarrior (task binary only) to be skipped (TestCase) TASK_USE_PATH -> Causes tests to look for "task" in PATH instead of the default location
