add a flag of fuzzy_parse, if the json file all object keys are the same and has same order, we only need to parse the first row, and then use index instead key to parse value
- There is a fe configuration called dynamic_partition_enable
which controls the opening and closing of the dynamic partition function.
When this configuration is false, it means that all tables do not support dynamic partitioning.
- But when the user tried to create the dynamic partition table, Doris did not detect this parameter.
This will cause the user can normally create a dynamic partition table,
but in fact Doris cannot create a partition for this table.
- This pr detect this config when building the table.
The dynamic partition table can be created only when the dynamic_partition_enable configuration is true.
If the configuration is false, the command to create a dynamic partition table will directly report an error.
1. Support modify column type CHAR to TINYINT/SMALLINT/INT/BIGINT/LARGEINT/FLOAT/DOUBLE/DATE
and TINYINT/SMALLINT/INT/BIGINT/LARGEINT/FLOAT/DOUBLE convert to a wider range of numeric types (#4937)
2. Use template to refactor code of types.h and schema_change.cpp to delete redundant code.
The name and another config name are close to each other and are indistinguishable.
So this pr modify the name.
The document description has also been changed
Support new synatx CREATE TABLE [IF NOT EXISTS] [db_name].table_name AS [db_name2].table_name2;
to create a new table from existed table with same table schema.

This PR is to add inPredicate support to delete statement,
and add max_allowed_in_element_num_of_delete variable to
limit element num of InPredicate in delete statement.
Support ALTER ROUTINE LOAD JOB stmt, for example:
```
alter routine load db1.label1
properties
(
"desired_concurrent_number"="3",
"max_batch_interval" = "5",
"max_batch_rows" = "300000",
"max_batch_size" = "209715200",
"strict_mode" = "false",
"timezone" = "+08:00"
)
```
Details can be found in `alter-routine-load.md`
This PR is mainly do three things:
1. Fix fe meta version bug introduced by #4029 , when fix conflict with #4086
2. Make drop check code easy to read
3. Add doc content for drop meta check
This PR is to support grammar like the following: INSTALL PLUGIN FROM [source] [PROPERTIES("KEY"="VALUE", ...)]
user can set md5sum="xxxxxxx", so we don't need to provide a md5 uri.
[Bug]Fix some schema change not work right
This CL mainly fix some schema change to varchar type not work right
because forget to logic check && Add ConvertTypeResolver to add
supported convert type in order to avoid forget logic check
This CL mainly changes:
1. Reorganized the code logic to limit the supported json format to two, and the import behavior is more consistent.
2. Modified the statistical behavior of the number of error rows when loading in json format, so that the error rows can be counted correctly.
3. See `load-json-format.md` to get details of loading json format.
Currently we choose BE random without check disk is available,
the create table will failed until create tablet task is sent to BE
and BE will check is there has available capacity to create tablet.
So check backend disk available by storage medium will reduce unnecessary RPC call.
