Support create/drop global function.
When you create a custom function, it can only be used within in one database. It cannot be used in other database/catalog. When there are many databases/catalog, it needs to create function one by one.
## Problem summary
Describe your changes.
1、 When a function is created or deleted, add the global keyword.
CREATE [GLOBAL] [AGGREGATE] [ALIAS] FUNCTION function_name (arg_type [, ...]) [RETURNS ret_type] [INTERMEDIATE inter_type] [WITH PARAMETER(param [,...]) AS origin_function] [PROPERTIES ("key" = "value" [, ...]) ]
DROP [GLOBAL] FUNCTION function_name (arg_type [, ...])
2、A completely global global function is set, and the global function metadata is stored in the image. The function lookup strategy is to look in the database first, and if it can't be found, it looks in the global function.

* 1. update ndv in Stats,
2. skip __DORIS_DELETE_SIGN__=0 in stats derive,
3. equalTo in stats derive
4. update agg stats derive, support the case: all column_stats are unknown
* computeSize
* fix ut
Before this PR when encountering null values with some columns which is specified as `NOT NULL`, null values will not be filtered,thi behavior does not match with the original load behavior.
Second column alignment logic has bug :
```
template <typename ColumnInserterFn>
void align_variant_by_name_and_type(ColumnObject& dst, const ColumnObject& src, size_t row_cnt,
ColumnInserterFn inserter) {
CHECK(dst.is_finalized() && src.is_finalized());
// Use rows() here instead of size(), since size() will check_consistency
// but we could not check_consistency since num_rows will be upgraded even
// if src and dst is empty, we just increase the num_rows of dst and fill
// num_rows of default values when meet new data
size_t num_rows = dst.rows();
```
basic functions for map datatype:
- MAP<K, V> map(K k1, V v1, ...)
- BIGINT map_size(MAP<K, V> m)
- BOOL map_contains_key(MAP<K, V> m, K k1)
- BOOL map_contains_value(MAP<K, V> m, V v1)
- ARRAY< K> map_keys(MAP<K, V> m)
- ARRAY< V> map_values(MAP<K, V> m)
How it works?
Aspectj is used to implement the aspect function of annotations. During the compilation process, the aspectj-maven-plugin plugin will automatically weave the code with aspect annotations into the generated classes file.
When to use to?
When a method wants to add a try catch to save exception information, the LogException annotation can be used. When there is a method that does not allow errors, the NoException annotation can be used.
What is the result when adding this annotation?
Use the LogException annotation to automatically capture exceptions into the Log file, and the code can be more concise. Use the NoException annotation to automatically capture the exception to the Log file and exit the program when an exception occurs.
will get String index out of range exception when use error datetime values like '2020-02-01'
before:
MySQL [test]> select test121.k1 from test121 where k1 != ('9102-12-');
ERROR 1105 (HY000): errCode = 2, detailMessage = Unexpected exception: String index out of range: 8
after:
MySQL [test]> select test121.k1 from test121 where k1 = '9102-12-';
ERROR 1105 (HY000): errCode = 2, detailMessage = Incorrect datetime value: '9102-12-' in expression: k1 = '9102-12-'

* [enhancement](fe query schedule) use try write lock to avoid too much wait time for planner; prin acii id instead of big int

aggregate_strategies execution too slow, use smaller table valued function to speed up
add a p2 case nereids_syntax_p2/aggregate_strategies to use larger table valued function to ensure correct
remove case nereids_syntax_p0/test_join_nereids since it redundant with nereids_p0/join/test_join
remove unstable case in query_p0/aggregate/aggregate
transient size may not equal to candidate_rowset size.
For example, one rowset has many segment, but size is smaller then
promotion size, this rowset will break pick rowset loop cause compaction
score is enough but will be filtered in level_size check, this will make
transient size not equal to candidate size.
When compaction case, memory map offsets coming to same olap convertor which is from 0 to 0+size
but it should be continue in different pages when in one segment writer .
eg :
last block with map offset : [3, 6, 8, ... 100]
this block with map offset : [5, 10, 15 ..., 100]
the same convertor should record last offset to make later coming offset followed last offset.
so after convertor :
the current offset should [105, 110, 115, ... 200], then column writer just call append_data() to make the right offset data append pages
1. Add Http interface for query q-error
2. Fix the selectivity calculation of inner join, it would always be 0 if there is only one join condition before
The problem is an exception when doing analyze:
java.lang.IllegalStateException: exceptions :
errCode = 2, detailMessage = select list expression not produced by aggregation output (missing from GROUP BY clause?): xxx
The scenario is:
select aes_decrypt(xxx,xxx) as c0 from table group by c0;
Analyze of problem:
The direct problem is mismatched of slotref, and this mismatched due to the mismatched of parameter number of aes_decrypt function. When debuging, we can see the slotref of group column is added to ExprSubstitutionMap, but can not matching with select result columns. And this is because when substiting expr it will analyze again, so the parameter would be added twice. This will cause the mismatching of function, so it would not be substitute as a slotref, the exception would be throw.
Fix:
Add call once to adding third parameter of aes_decrypt type function. Compare the child we want to add to the last child of function. If they are the same, do not add it.
* when add two not exist fe and drop two not exit fe, we may meet exception like this:
