Deprecating ResolveRepositoryName

Passing RepositoryInfo to ResolveAuthConfig, pullRepository, and pushRepository

Moving --registry-mirror configuration to registry config

Created resolve_repository job

Repo names with 'index.docker.io' or 'docker.io' are now synonymous with omitting an index name.

Adding test for RepositoryInfo

Adding tests for opts.StringSetOpts and registry.ValidateMirror

Fixing search term use of repoInfo

Adding integration tests for registry mirror configuration

Normalizing LookupImage image name to match LocalName parsing rules

Normalizing repository LocalName to avoid multiple references to an official image

Removing errorOut use in tests

Removing TODO comment

gofmt changes

golint comments cleanup.  renaming RegistryOptions => registry.Options, and RegistryServiceConfig => registry.ServiceConfig

Splitting out builtins.Registry and registry.NewService calls

Stray whitespace cleanup

Moving integration tests for Mirrors and InsecureRegistries into TestNewIndexInfo unit test

Factoring out ValidateRepositoryName from NewRepositoryInfo

Removing unused IndexServerURL

Allowing json marshaling of ServiceConfig.  Exposing ServiceConfig in /info

Switching to CamelCase for json marshaling

PR cleanup; removing 'Is' prefix from boolean members.  Removing unneeded json tags.

Removing non-cleanup related fix for 'localhost:[port]' in splitReposName

Merge fixes for gh9735

Fixing integration test

Reapplying #9754
