Summary: Some repos are push-redirected repos: pushes go to another repos, but then synced into this repo. Because of this, when we import a repo into a smaller repo that push-redirects to a large repo, we need to make sure we don't break the large repo with the imported code, since merges, pushes, imports etc. are redirected to the large repo. For now, in order to avoid breaking the large repo, we added a simple check that returns error, if the small repo push-redirects to the large one.

Summary:
After creating the merge commit (D23028163 (f267bec3f7)) from the imported commit head and the destination bookmark's head, we need to push the commit onto that bookmark. This diff adds the push functionality to repo_import tool.
Note: GlobalrevPushrebaseHook is a hook to assign globalrevs to commits to keep the order of the commits

Summary:
Once we have revealed the commits to the user (D22864223 (578207d0dc), D22762800 (f1ef619284)), we need to merge the imported branch into the destination branch (specified by dest-bookmark). To do this, we extract the latest commit of the destination branch, then compare the two commits, if we have merge conflicts. If we have merge conflicts, we inform the user, so they can resolve it. Otherwise, we create a new bonsai having the two commits as parents.
Next step: pushrebase the merge commit
Minor refactor: moved app setup to a separate file for better readability.

Related diff: D22816538 (3abc4312af)
In repo_import tool once we move a bookmark to reveal commits to users, we want to check if hg_sync has received the commits. To do this, we extract the largest log id from bookmarks_update_log to compare it with the mutable_counter value related to hg_sync. If the counter value is larger or equal to the log id, we can move the bookmark to the next batch of commits. Otherwise, we sleep, retry fetching the mutable_counter value and compare the two again.
mutable_counters is an sql table that can track bookmarks log update instances with a counter.
This diff adds the functionality to extract the mutable_counters value for hg_sync.
======================
SQL query fix:
In the previous diff (D22816538 (3abc4312af)) we didn't cover the case where we might not get an ID which should return None. This diff fixes this error.

Summary:
Once we start moving the bookmark across the imported commits (D22598159 (c5e880c239)), we need to check dependent systems to avoid overloading them when parsing the commits. In this diff we added the functionality to check Phabricator. We use an external service (jf graphql - find discussion here: https://fburl.com/nr1f19gs) to fetch commits from Phabricator. Each commit id starts with "r", followed by a call sign (e.g FBS for fbsource) and the commit hash (https://fburl.com/qa/9pf0vtkk). If we try to fetch an invalid commit id (e.g not having a call sign), we should receive an error. Otherwise, we should receive a JSON.
An imported commit should have the following query result: https://fburl.com/graphiql/20txxvsn - nodes has one result with the imported field true.
If the commit hasn't been recognised by Phabricator yet, the nodes array will be empty.
If the commit has been recognised, but not yet parsed, the imported field will be false.
If we haven't parsed the batch, we will try to check Phabricator again after sleeping for a couple of seconds.
If it has parsed the batch of commits, we move the bookmark to the next batch.

Summary: D22381744 updated the version of `futures` in third-party/rust to 0.3.5, but did not regenerate the autocargo-managed Cargo.toml files in the repo. Although this is a semver-compatible change (and therefore should not break anything), it means that affected projects would see changes to all of their Cargo.toml files the next time they ran `cargo autocargo`.

Previous commit: D22233127 (fa1caa8c4e)
In this diff, I added rewrite commit path functionality using Mover https://fburl.com/diffusion/6rnf9q2f to repo_import.
Given a prefix (e.g. new_repo), we prepend the paths of the files extracted from the bonsaichangesets given by gitimport (e.g. folder1/file1 => new_repo/folder1/file1). Previously, we did this manually when importing a git repo (https://www.internalfb.com/intern/wiki/Mercurial/Admin/ImportingRepos/) using convert extension.
