Slash should be escaped in route values

[soemiran]

Route dict is apparently used as a convenience to build URLs for parts between slashes. So it seems appropriate to escape slash (/) especially when values contain slashes on purpose.

NB: Not using routes with GhApi(path) by passing escaped string as path is an acceptable workaround but it does not work when leveraging paged method which either does not escape slash when passed as is, or escapes "%2F" when an escaped string is passed:

This does not work:

api = GhApi()
img_name = "ns/img"
img_versions = api('/orgs/{org}/packages/container/{img_name}/versions', 'GET', route=dict(org="org", img_name=img_name))

Working around works:

api = GhApi()
img_name = "ns/img"
img_versions = api('/orgs/{org}/packages/container/%s/versions' % urllib.parse.quote(img_name, safe=''), 'GET', route=dict(org="org"))

Using paged fails as endpoint does not exist when not escaped:

api = GhApi()
img_name = "ns/img"
img_versions_pages = paged(api.packages.get_all_package_versions_for_package_owned_by_org, org="org", package_type="container", package_name=img_name)

Using paged fails as package does not exist when escaped

api = GhApi()
img_name = "ns/img"
img_versions_pages = paged(api.packages.get_all_package_versions_for_package_owned_by_org, org="org", package_type="container", package_name=urllib.parse.quote(img_name, safe=''))
