Previously setting `enable_order_by_all` distinguished for ORDER BY ALL
whether we should sort by column 'all' (if given in the SELECT clause)
or by all columns. The actual behavior was not always intuitive.
Now, we throw unconditionally an exception which also simplifies the
handling a bit. Only an edge case is affected and if users really want
to run ORDER BY ALL on a column names 'all', they can alias it.

I've recently stumbled several times trying to figure out where to put the `SETTINGS` when inserting `VALUES` and `FROM INFILE`, so I'm clarifying it here in the docs.
Add syntax in SQL and XML to mark specific fields to allow
override or not.
Also add a new setting to control the default behaviour when
overriding support is not specified.
* Limit log frequence for "Skipping send data over distributed table" message
After SYSTEM STOP DISTRIBUTED SENDS it will constantly print this
message.

* Rename directory monitor concept into async INSERT
Rename the following query settings (with preserving backward
compatiblity, by keeping old name as an alias):
- distributed_directory_monitor_sleep_time_ms -> distributed_async_insert_sleep_time_ms
- distributed_directory_monitor_max_sleep_time_ms -> distributed_async_insert_max_sleep_time_ms
- distributed_directory_monitor_batch -> distributed_async_insert_batch_inserts
- distributed_directory_monitor_split_batch_on_failure -> distributed_async_insert_split_batch_on_failure
Rename the following table settings (with preserving backward
compatiblity, by keeping old name as an alias):
- monitor_batch_inserts -> async_insert_batch
- monitor_split_batch_on_failure -> async_insert_split_batch_on_failure
- directory_monitor_sleep_time_ms -> async_insert_sleep_time_ms
- directory_monitor_max_sleep_time_ms -> async_insert_max_sleep_time_ms
And also update all the references:
$ gg -e directory_monitor_ -e monitor_ tests docs | cut -d: -f1 | sort -u | xargs sed -e 's/distributed_directory_monitor_sleep_time_ms/distributed_async_insert_sleep_time_ms/g' -e 's/distributed_directory_monitor_max_sleep_time_ms/distributed_async_insert_max_sleep_time_ms/g' -e 's/distributed_directory_monitor_batch_inserts/distributed_async_insert_batch/g' -e 's/distributed_directory_monitor_split_batch_on_failure/distributed_async_insert_split_batch_on_failure/g' -e 's/monitor_batch_inserts/async_insert_batch/g' -e 's/monitor_split_batch_on_failure/async_insert_split_batch_on_failure/g' -e 's/monitor_sleep_time_ms/async_insert_sleep_time_ms/g' -e 's/monitor_max_sleep_time_ms/async_insert_max_sleep_time_ms/g' -i

* Rename async_insert for Distributed into background_insert
This will avoid amigibuity between general async INSERT's and INSERT
into Distributed, which are indeed background, so new term express it
even better.
Mostly done with:
$ git di HEAD^ --name-only | xargs sed -i -e 's/distributed_async_insert/distributed_background_insert/g' -e 's/async_insert_batch/background_insert_batch/g' -e 's/async_insert_split_batch_on_failure/background_insert_split_batch_on_failure/g' -e 's/async_insert_sleep_time_ms/background_insert_sleep_time_ms/g' -e 's/async_insert_max_sleep_time_ms/background_insert_max_sleep_time_ms/g'

Before it was impossible to update Protobuf schema without server
restart. With this commit, it is enough to send query `SYSTEM DROP
SCHEMA FORMAT CACHE [FOR Protobuf]`.
Added new type of authentication based on SSH keys. It works only for Native TCP protocol.

Accepts CH client queries in the form of
SHOW FUNCTIONS [LIKE | ILIKE '< pattern>']
Retrieves all columns from `functions` table in system database.
Fixes#52757
I propose changes to make it clear that CTEs do not guarantee the same results in all places they are used, since the query will be re-executed in each place they are used.
