This worklog addresses the following functional requirements:
* Provide a global command-line server startup option
 --disabled-storage-engines which accepts comma delimited
storage engine names. DDL's which end-up creating new table
or tablespace on these engines will be disallowed.
Specifically,  'CREATE [TEMPORARY] TABLE', 'ALTER TABLE ... ENGINE'
and 'CREATE/ALTER TABLESPACE' using one of above engine.

* The SQL statements  'CREATE [TEMPORARY] TABLE',
'ALTER TABLE ... ENGINE' and 'CREATE/ALTER TABLESPACE'
shall fail with the error "Storage engine 'storage engine name'
is disabled (Table creation is disallowed.)" for the storage
engines specified by disabled-storage-engine option. This
option shall be noop and will have no effect when the
server is either started with --bootstrap or
--skip-grant-tables options.

* This option does not affect any other DDL statements except
for, 'CREATE [TEMPORARY] TABLE', 'ALTER TABLE ... ENGINE' and
'CREATE/ALTER TABLESPACE'

* This option shall be noop and will have no effect when the
server is either started with --bootstrap or --initialize or
--initialize-insecure or --skip-grant-tables. The bootstrap
and related options are used by sys admin to initialize
system tables to prepare the server to operate normally and
--skip-grant-tables is meant to provide full control with
no authorization required.
