* feat: go-like import style
jb now creates a directory structure inside of vendor/ that is similar to how go
does (github.com/grafana/jsonnet-libs). This is reflected in the final import
paths, which means they will be go-like
* refactor(spec/deps): named regexs
* feat: make goImportStyle configurable
Defaults to off, can be enabled in `jsonnetfile.json`
* fix: integration test
* doc: license headers
* fix(deps): remove GO_IMPORT_STYLE
not an option anymore, will always do so and symlink
* feat: symlink to legacy location
* feat: allow to disable legacy links
* fix(test): legacyImports in integration tests
* fix(spec): test
* fix: respect legacyName aliases
It was possible to alias packages by changing `name` previously.
While names are now absolute (and computed), legacy links should still respect
old aliases to avoid breaking code.
* fix(test): integration
* fix(init): keep legacyImports enabled for now
* feat: rewrite imports
adds a command to automatically rewrite imports from legacy to absolute style
* fix(tool): rewrite confused by prefixing packages
When a package was a prefix of another one, it broke.
Fixed that by using a proper regular expression. Added a test to make sure it
works as expected
* Update cmd/jb/init.go
* fix: exclude local packages from legacy linking
They actually still use the old style, which is fine. LegacyLinking
messed them up, but from now on it just ignores symlinks that match a localPackage.
So far, `pkg` and `pkg/jsonnetfile` had overlapping functionality when it came
to choosing and loading jsonnetfiles.
This fully switches to the separate package `pkg/jsonnetfile` that seems to be
created for exactly this purpose
