infinitepush: drop the `--create` flag to push command The extension added a `--create` flag for creating a new bookmark on the bundlestore. This patch changes the bahviour to create a bookmark if it does not exists and removes the requirement of the `--create` and then drop the logic around the `--create` flag. Tests are changed to drop the usage of `--create` flag. Differential Revision: https://phab.mercurial-scm.org/D2107

infinitepush: drop hack related to --to, --create flags of remotenames-ext The remotenames extension has --to, --create. --allow-anon flags which won't be ported to core.

infinitepush: drop error handling while pushing to svn server This is something which is internal to Facebook and we don't want in core. Differential Revision: https://phab.mercurial-scm.org/D2104

infinitepush: drop `--list-remote`, `--remote-path` flags to bookmark cmd The extension adds these two flags to list remote bookmarks using the `hg bookmark` command. These are not required in core currently and needs some discussion before getting them in, so let's drop them for now. This makes us deleting the wrapping of `hg bookmark` command on client side. The end goal here is to have minimal or no wrapping at client side. Differential Revision: https://phab.mercurial-scm.org/D2103

infinitepush: drop the scratchbookmarksparttype bundle2 part The scratchbookmarksparttype bundle2 part was used in backupcommands.py which we deleted in an earlier changeset.

infinitepush: remove wrapping around bundle2._addpartsfromopts() This wrapping around bundle2._addpartsfromopts() was added by me while hacking on an alternate way to mark a push as infinitepush or not. However the wrapping is wrong as the push command does not go through the code path which was wrapped on the client side. Differential Revision: https://phab.mercurial-scm.org/D2101

infinitepush: delete the bundle2 part ordering related to pushrebase pushrebase is another Facebook extension which does not live in core yet. So let's remove the logic which make sures infinitepush part is moved before the pushrebase one. Differential Revision: https://phab.mercurial-scm.org/D2100

infinitepush: delete the hack to load the extension after remotenames The remotenames extension which circumvents the default push implementation lives outside the core, so let's delete logic related to loading of extension on the basis of remotenames ext.
