Init iotdb, part Query not completed
1. pkg\query\iotdb.go added, but not completed yet
2. cmd\...\iotdb\common.go added, but not completed yet
3. cmd\...\iotdb\devops.go added, but not completed yet
4. go.mod and go.sum modified

1. complete devops.go. without devops_test.go
Other files are not completed so it may cannot generate queries till now.
2. fix some typo in internal\utils\time_interval.go

1. devops query generate completed.
2. test file added, but NOT completed

queries test complete

serializer complete

cmd/tsbs_load_iotdb

tsbs_load_iotdb is completed, but no unit tests added in this part

update iotdb-client-go version, use timeoutInMs

complete scan test
也许应该做更多努力来增强batch的性能

update some user friendly tips. timeout info, workers info.

Users can now specify timeout for session opening check

tsbs_run_queries_iotdb has been completed.
Some CRTODO comments need to be removed

CRTODO removed
using back quote(`) in IP address instead of using quotation marks(")

using DATETIME-INPUT in data serializer
timestamp in LONG INT is ambiguous

fix bug in GroupByTimeAndPrimaryTag
should use one hour in `group by` instead of one minute

added documentation, readme for iotdb

1.using InsertRecords
2.serilaizer string without ''
3.using unixNano as timestamp in serializer output file, but should be converted into millisecond before insert.
4.readme updated
5.there is 3 lines in serializer output for each data point

using 4lines structure for serializer, not completed
can insert data without tags.
can NOT handle tags yet in this commit.

using 4lines serializer
storage tags in attributes of node '_tags'

update workersNum warning in insertion test
less than five --> less than 2

optimize ProcessBatch function
using records struct to simplify code

fix typo parseDateToInterface -> parseDataToInterface

support csv export
but readme is not updated

make sure csv export can be used offline
if to-csv == true, then there is no need to connect to any database, because user want to generate csv files locally

updated docs and comments.
added arguments check
init bug fixed: forget to init ProcessedTagsDeviceIDMap in Init.

updated test cases for scan.go and serializer.go
return empty string while there is no tags

correct SQL queries.
support printing queries responses.

[important]
Printing is not counted into query time.
 Do NOT send close signal after each query.

updated main readme

fix bug:
query dataset did not close in all cases.
Now dataset will always close after query, and will be traversed in query

check dataset close error before return

better error catch for dataset closing

updated SQL query

close sql dataset in insertion

Traverse query results in insertion

fix defer ds.Close() in insertion

use ExecuteNonQueryStatement for inserting tags

close dataSet in queries anyway

for GroupByTime use 1min， fix issues timescale#214
IoTDB is same with InfluxDB and TimescaleDB now。
And that meas the behavior of IoTDB single-group-by queries is NOT same with README, but is same with other databases.

User can choose TS type and whether to store tags now.
Added flag `aligned-timeseries` and `store-tags` for tsbs_load_iotdb

after queries, not traverse query results

treat all integer as int32

do NOT treat all integer as int32

Fixed Bug, supported using BasicPath for data generation

Fix test cases TestSerialize_normal

Fix panic in timescale target with `iot` use case (timescale#233)
