Add galaxykit collection upload --skip-upload, --template

[himdel]

with --skip-upload, galaxykit just creates the file and returns the filename, without trying to upload it.

intended for generating artifacts for cypress e2e to upload, to test the UI paths

$ galaxykit collection upload --skip-upload
{"namespace": "admin", "name": "collection_dep_a_pntqbywn", "version": "1.0.0", "published": false, "filename": "/tmp/home/himdel/.local/lib/python3.11/site-packages/orionutils/collections/skeleton/admin-collection_dep_a_pntqbywn-1.0.0.tar.gz"}

$ ls -l /tmp/home/himdel/.local/lib/python3.11/site-packages/orionutils/collections/skeleton/admin-collection_dep_a_pntqbywn-1.0.0.tar.gz

(... | jq .filename to get just the filename)

(the collection template lives in https://github.com/peaqe/orion-utils/tree/master/orionutils/collections/skeleton)

---

Also allow --template to allow picking templates other than skeleton, from https://github.com/peaqe/orion-utils/tree/master/orionutils/collections

---

Also,

collection approve namespace name version
collection deprecate namespace name repository
collection undeprecate namespace name repository

Also..
