fcb651329c [Plugin] Making FE audit module pluggable (#3219) 
Currently we have implemented the plugin framework in FE. 
This CL make the original audit log logic pluggable.
The following classes are mainly implemented:

1. AuditPlugin
    The interface of audit plugin

2. AuditEvent
    An AuditEvent contains all information about an audit event, such as a query, or a connection.

3. AuditEventProcessor
    Audit event processor receive all audit events and deliver them to all installed audit plugins.

This CL implements two audit module plugins:

1. The builtin plugin `AuditLogBuilder`, which act same as the previous logic, to save the 
    audit log to the `fe.audit.log`

2. An optional plugin `AuditLoader`, which will periodically inserts the audit log into a Doris table
    specified by the user. In this way, users can conveniently use SQL to query and analyze this
    audit log table.

Some documents are added:

1. HELP docs of install/uninstall/show plugin.
2. Rename the `README.md` in `fe_plugins/` dir to `plugin-development-manual.md` and move
    it to the `docs/` dir
3. `audit-plugin.md` to introduce the usage of `AuditLoader` plugin.

14c088161c [New Stmt] Support setting replica status manually (#1522) 
Sometimes a replica is broken on BE, but FE does not notice that.
In this case, we have to manually delete that replica on BE.
If there are hundreds of replicas need to be handled, this is a disaster.

So I add a new stmt:

    ADMIN SET REPLICA STATUS

which support setting tablet on specified BE as BAD or OK.

c098178f7a [Index] Implements create drop show index syntax for bitmap index [#2487] (#2573) 
### create table with index 
```
CREATE TABLE table1
(
    siteid INT DEFAULT '10',
    citycode SMALLINT,
    username VARCHAR(32) DEFAULT '',
    pv BIGINT SUM DEFAULT '0',
    INDEX index_name [USING BITMAP] (siteid, citycode) COMMENT 'balabala'
)
AGGREGATE KEY(siteid, citycode, username)
DISTRIBUTED BY HASH(siteid) BUCKETS 10
PROPERTIES("replication_num" = "1");
```
### create index 
```
CREATE INDEX index_name  ON table1 (siteid, citycod) [USING BITMAP] COMMENT 'balabala';
or 
ALTER TABLE table1 ADD  INDEX index_name  [USING BITMAP] (siteid, citycod) COMMENT 'balabala';
```
### drop index
```
DROP INDEX index_name ON table1;
or
ALTER TABLE table1 DROP INDEX index_name 
```

### show index
```
SHOW INDEX[ES] FROM table1
```
output
```
+---------+-------------+-----------------+------------+---------+
| Table   | Index_name  | Column_name     | Index_type | Comment |
+---------+-------------+-----------------+------------+---------+
| table1  | index_name  | siteid,citycode | BITMAMP    | balabala|
