This work is in the early stage, current progress is not accurate because the scan range will be too large
for gathering information, what's more, only file scan node and import job support new progress manager
## How it works
for example, when we use the following load query:
```
LOAD LABEL test_broker_load
(
DATA INFILE("XXX")
INTO TABLE `XXX`
......
)
```
Initial Progress: the query will call `BrokerLoadJob` to create job, then `coordinator` is called to calculate scan range and its location.
Update Progress: BE will report runtime_state to FE and FE update progress status according to jobID and fragmentID
we can use `show load` to see the progress
PENDING:
```
State: PENDING
Progress: 0.00%
```
LOADING:
```
State: LOADING
Progress: 14.29% (1/7)
```
FINISH:
```
State: FINISHED
Progress: 100.00% (7/7)
```
At current time, full output of `show load\G` looks like:
```

## TODO:
1. The current partition granularity of scan range is too large, resulting in an uneven loading process for progress."
2. Only broker load supports the new Progress Manager, support progress for other query
