[Feature] Support exporting of telemetry data using python PE rest client

[gaurav36]

Description:
Currently we are missing support for some important feature in the python tb rest client version 1.4 , for eg: getting telemetry data

As i can see in github source code, we are not loading this telemetry module
[1] https://github.com/thingsboard/thingsboard-python-rest-client/blob/master/tb_rest_client/rest_client_pe.py#L1567&#L1608

Expected behavior:
User should be able to get telemetry data using python rest client.

Additional Information:
python rest client version: 1.4

Hi @gaurav36, rest client support getting telemetry:

For example:
rest_client.get_latest_timeseries(EntityId('d1cfaff0-a390-11ec-8112-ad8278896f52', 'DEVICE'))

@samson0v Thanks for this update. Do you have any documentation of this API ?

In the python rest client https://paste.ubuntu.com/p/psFJq4pwfB/ I am using the PEca client and in the error logs its using api_ce https://paste.ubuntu.com/p/gY4K3zyBPC/

here I am passing arg1: file_name_to_save_timeseries_data, arg2: tenant_id, arg3: keys, arg4: start_time, arg5: endtime

I even tried, but its giving empty results (res={})
res = rest_client.get_timeseries(EntityId('my_tenant_id', 'TENANT'), keys="epc,locationId", start_ts="1660037511000", end_ts="1661247111000")
print("latest timeseries from tenant is: {}".format(res))

May be you can write here full api call for getting timeseries data from particular tenant.
for eg: rest_client.get_timeseries(entity_id=entityId, keys=keys, start_ts=startTs, end_ts=endTs)
