CLICKHOUSE-784: reset merge tree setting 
Add an ability to reset custom setting to default and remove it from table's metadata.
This will allow to rollback the change without knowing the system/config's default.

Projections 
TODO (suggested by Nikolai)

1. Build query plan fro current query (inside storage::read) up to WithMergableState
2. Check, that plan is simple enough: Aggregating - Expression - Filter - ReadFromStorage (or simplier)
3. Check, that filter is the same as filter in projection, and also expression calculates the same aggregation keys as in projection
4. Return WithMergableState if projection applies

3 will be easier to do with ActionsDAG, cause it sees all functions, and dependencies are direct (but it is possible with ExpressionActions also)

Also need to figure out how prewhere works for projections, and
row_filter_policies.

5c83b09a2f disallow CODEC setting for column type ALIAS 
This commit adds checks in place during table creation
and updates to ensure that we don't allow `CODEC` for
ALIAS (`default_type` column) like:

```sql
CREATE TABLE compression_codec_on_alias
(
    `c0` ALIAS c1 CODEC(ZSTD),
    `c1` UInt64
)
ENGINE = MergeTree()
PARTITION BY c0
ORDER BY c1;
```

After these safeguards in place, when trying to create/update column
codec, we will get excaptions like this:

```sql

-- create

CREATE TABLE compression_codec_on_alias
(
    `c0` ALIAS c1 CODEC(ZSTD),
    `c1` UInt64
)
ENGINE = MergeTree()
PARTITION BY c0
ORDER BY c1

Received exception from server (version 20.8.1):
Code: 377. DB::Exception: Received from localhost:9000. DB::Exception: Cannot specify codec for column type ALIAS.

0 rows in set. Elapsed: 0.006 sec.

-- modify

ALTER TABLE compression_codec_on_alias
    ADD COLUMN `c3` ALIAS c2 CODEC(ZSTD) AFTER c2

Received exception from server (version 20.8.1):
Code: 377. DB::Exception: Received from localhost:9000. DB::Exception: Cannot specify codec for column type ALIAS.

0 rows in set. Elapsed: 0.005 sec.
