Refactor SD configuration to remove `config` dependency (#3629) * refactor: move targetGroup struct and CheckOverflow() to their own package * refactor: move auth and security related structs to a utility package, fix import error in utility package * refactor: Azure SD, remove SD struct from config * refactor: DNS SD, remove SD struct from config into dns package * refactor: ec2 SD, move SD struct from config into the ec2 package * refactor: file SD, move SD struct from config to file discovery package * refactor: gce, move SD struct from config to gce discovery package * refactor: move HTTPClientConfig and URL into util/config, fix import error in httputil * refactor: consul, move SD struct from config into consul discovery package * refactor: marathon, move SD struct from config into marathon discovery package * refactor: triton, move SD struct from config to triton discovery package, fix test * refactor: zookeeper, move SD structs from config to zookeeper discovery package * refactor: openstack, remove SD struct from config, move into openstack discovery package * refactor: kubernetes, move SD struct from config into kubernetes discovery package * refactor: notifier, use targetgroup package instead of config * refactor: tests for file, marathon, triton SD - use targetgroup package instead of config.TargetGroup * refactor: retrieval, use targetgroup package instead of config.TargetGroup * refactor: storage, use config util package * refactor: discovery manager, use targetgroup package instead of config.TargetGroup * refactor: use HTTPClient and TLS config from configUtil instead of config * refactor: tests, use targetgroup package instead of config.TargetGroup * refactor: fix tagetgroup.Group pointers that were removed by mistake * refactor: openstack, kubernetes: drop prefixes * refactor: remove import aliases forced due to vscode bug * refactor: move main SD struct out of config into discovery/config * refactor: rename configUtil to config_util * refactor: rename yamlUtil to yaml_config * refactor: kubernetes, remove prefixes * refactor: move the TargetGroup package to discovery/ * refactor: fix order of imports
