At present, when some rpc errors occur, the client cannot obtain the error information well.
And this CL change the RPC error returned to client like this:
```
ERROR 1064 (HY000): errCode = 2, detailMessage = there is no scanNode Backend. [10002: in black list(A error
occurred: errorCode=2001 errorMessage:Channel inactive error!)]
ERROR 1064 (HY000): failed to send brpc batch, error=The server is overcrowded, error_text=[E1011]The server is
overcrowded @xx.xx.xx.xx:8060 [R1][E1011]The server is overcrowded @xx.xx.xx.xx:8060 [R2][E1011]The server is
overcrowded @xx.xx.xx.xx:8060 [R3][E1011]The server is overcrowded @xx.xx.xx.xx:8060, client: yy.yy.yy.yy
```
This is the last PR of proposal #4308
1. Add a new FE config `enable_http_server_v2` to enable new HTTP Server implementation. The default value is false.
2. Add a new FE config `http_api_extra_base_path` so that we can set base path for Frontend UI.
3. Refactor the new HTTP API response body. The return http status code is always 200, and using internal code in response body to indicate the certain error.
1. Support limit clause push down both odbc table and mysql table.
2. Code refactor of ODBC Scan Node, change `build_connect_string` and `query_string` from BE to FE to make it easily to modify
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.
ISSUE: #4355
Fix#4692
The reason of this bug is case-when statement may produce implicit CastExpr<SlotRef>
as SelectListItem in analyze step.
And these CastExpr<SlotRef> in SelectList will not be re-anlyze after rewrite step,
which will result in the incorrect number of self-incrementing SlotDescriptor ID in resultExprs .
So we need to reset the analysis state of CastExpr<SlotRef> in rewrite step.
when a dynamic partitioned table is created, it will take some time to create the partitions.
A exception needs to be thrown when users try to load data into this table,
otherwise the load will stuck in loading phase all the time.
After BE down, transactions related should be cleared.
The hostname is used to retrive the transactions.
But hostname is recorded as hostname + port, the port
should be removed.
When forwarding show tablet stmt to Master FE. If the result contains null, FE will throw exception.
Fix it by using `\N` instead of "null" in result, to make thrift rpc happy.

issue #4501
Use spring mvc rest to replace the original netty http rest
Created a new package `org/apache/doris/httpv2`,
and the origin implementations under `org/apache/doris/http` remain unchanged.
This part of the code will not be used at present, so it will not affect existing functions.
API document can be found in #4584
Proposal #4308
* [Bug]Fix bug that tablet info with wrong capacity may cause fe oom
* remove unused code
* fix
* remove empty line

For[Spark Load]
1 support decimal andl largeint
2 add validate logic for char/varchar/decimal
3 check data load from hive with strict mode
4 support decimal/date/datetime aggregator
When Doris create a database, the database of data quota and replica quota is initialized by configuration(Config.default_db_data_quota_bytes and Config.default_db_replica_quota_bytes).
In other words, I convert FeConstants.default_db_data_quota_bytes to Config.default_db_data_quota_bytes
Config.default_db_data_quota_bytes can be change in configuration file.
When fe replay rollup job(v1) with deleted table, it will throw null pointer exception and exit.
This commit ignore this error and print a warning log to avoid fe exit.
