By way of having an implementation of `data_dictionary` and using that.
The schema loader only needs a database to parse cql3 statements, which
are all coordinator-side objects and hence been largely migrated to use
data dictionary instead.
A few hard-dependencies on replica:: objects were found and resolved:
* index::secondary_index_manager
* tombstone_gc
The former was migrated to use `data_dictionary::table` instead of
`replica::table`. This in turn requires disentangling
`replica::data_dictionary_impl` from `replica::database`, as currently
the former can only really be used by the latter.
What all of this achieves us is that we no longer have to instantiate a
`replica::database` object in `tools::load_schema()`. We want to use the
standard allocator in tools, which means they cannot use LSA memory at
all. Database on the other hand creates memtable and row-cache instances
so it had to go.
