Pull parameter_types! from metadata (#1066)

* @polkadot/{extrinsics,storage} moved to @polkadot/metadata * Fix previous commit * Fix previous commit * Expose parameter types using api.consts * Grumbles; update v6 static metadata; add UncleEntryItem (fix #1067) * Update api.query.* to api.consts.* where changed * Update tests and stray api.query.staking.sessionsPerEra * Grumbles * Grumbles * Revert updates to api-derive (taken care of by #1068) * Grumbles; fix UncleEntryItem * Rename "@polkadot/metadata" => "@polkadot/api-metadata" * Skip derive test * Grumbles * Grumbles * Grumbles * Cleanup merge, ensure metadata is latest * Move api-metadata to actual api-metadata folder * README api-metadata description (& folder link) * Remove stray type-extrinsics package.json

-      the Derivative Works; and
-
-  (d) If the Work includes a "NOTICE" text file as part of its

-      wherever such third-party notices normally appear. The contents
-      of the NOTICE file are for informational purposes only and
-      do not modify the License. You may add Your own attribution
-      notices within Derivative Works that You distribute, alongside
-      or as an addendum to the NOTICE text from the Work, provided
-      that such additional attribution notices cannot be construed

-  origin of the Work and reproducing the content of the NOTICE file.
-
-7. Disclaimer of Warranty. Unless required by applicable law or
-  agreed to in writing, Licensor provides the Work (and each
-  Contributor provides its Contributions) on an "AS IS" BASIS,
-  WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
-  implied, including, without limitation, any warranties or conditions
-  of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
-  PARTICULAR PURPOSE. You are solely responsible for determining the
-  appropriateness of using or redistributing the Work and assume any
-  risks associated with Your exercise of permissions under this License.
-
-8. Limitation of Liability. In no event and under no legal theory,
-  whether in tort (including negligence), contract, or otherwise,
-  unless required by applicable law (such as deliberate and grossly
-  negligent acts) or agreed to in writing, shall any Contributor be
-  liable to You for damages, including any direct, indirect, special,
-  incidental, or consequential damages of any character arising as a
-  result of this License or out of the use or inability to use the

-  of your accepting any such warranty or additional liability.
