Infrastructure changes to support scoped symbols

Summary:
 - import_project_symbols supports an optional extra field, which is the
   context of the symbol.
 - Symbol query can take a symbol argument, either as a parameter or a
   URL component (so you can now jump nav to `s Zerg/rush`, for
   example).
 - Conduit method not yet updated. Will do that later.

NOTE: Not providing a context is distinct from providing an empty
context, because an empty context stands for top-level context, i.e.
functions and classes for PHP. It will not find class methods, etc. It
is possible that we should use some weird token that could not normally
be a context name to stand in for empty context.

Test Plan: Do a bunch of symbol searches.
