Bugzilla

Updating what data we'll be hooking up to the Lockwise card in this issue, based on the [mockups](https://treeherder.mozilla.org/#/jobs?repo=try&revision=f05b7d2f845f63168e46af11e7b6e2fabb4e4c15). In Bug 1559418, we have already implemented counting the number of stored logins via `Services.logins.countLogins`. So now what's left is to display the number of synced devices linked to the user's account. We've been provided with some good places to start (thanks Ryan Kelly!): 

- The simplest approach is to ping the server everytime the page is loaded using [getDeviceAccountsList()](https://dxr.mozilla.org/mozilla-central/rev/6a2bd09a6bf9aada14581e923408d7308479b76d/services/fxaccounts/FxAccounts.jsm#751) from `FxAccounts.jsm`.
- To avoid doing this, we'll need to take some extra steps, which Ryan has also provided:
```
1) Checking whether sync has already loaded the list of devices in the background:

2) If it hasn't, showing some placeholder UI and triggering a sync:

3) Getting the list of devices out of sync's "clients" engine, which has a local cache of it:
