- remove dep on consul main module - use 'consul tls' subcommands instead of tlsutil - use direct json config construction instead of agent/config structs - merge libcluster and libagent packages together - more widely use BuildContext - get the OSS/ENT runner stuff working properly - reduce some flakiness - fix some correctness related to http/https API
