Add FOLIO keyboard shortcuts to Agreements-Platforms

Stripes incorporates a set of keyboard shortcut keys for implementation across all apps. See:

• Section "Platform-wide keyboard shortcuts (each app must implement) " on the wiki page Key Navigation https://wiki.folio.org/display/A11Y/Keyboard+Navigation
• Keyboard commands API: https://github.com/folio-org/stripes-components/tree/master/lib/Commander

The following shortcuts should be implemented in Agreements-Platforms:

1. Expand all accordions on detail record (focus must be on any element on the detail record) - cmd / ctrl + alt + b
2. Collapse all accordions on detail record (focus must be on any element on the detail record) - cmd / ctrl + alt + g
3. Edit selected detail record (focus must be on any element on the detail record) - cmd / ctrl + alt + e
4. Save edit / new form changes (focus must be on any element on the detail record) - cmd / ctrl + s
5. Go to Search & Filter pane (aka first pane) - cmd / ctrl + alt + h

Refer to the Users app and also the implementation of shortcut keys in Agreements as part of ERM-1151 for example implementations.
