improvement: add create_table_options for partitioned tables and more

[rgraff]

Description

Adds a create_table_options option to the DSL that is used by migration generator to pass the option to table/2. Note that the option's name is options and it is a string.

### resource defintion
postgres do
  table "posts"
  create_table_options "PARTITION BY RANGE (inserted_at)"
end

### migration looks like
create table(:posts, options: "PARTITION BY RANGE (inserted_at)") do
   ...
end

Also includes some documentation for partitioned tables. Note that partitioned tables can only be created with CREATE TABLE and not ALTER TABLE, so this change is the only practical way to generate a partitioned table with the generator.
