Description

In some occasions, we may need to define aligned timeseries such as:

create aligned timeseries root.sg.d1.(s1 FLOAT, s2 INT32) 
with encoding=(RLE, Grollia), compression=SNAPPY

To avoid create timeseries repeatedly when a number of devices / storage groups have same sensors, we intend to introduce the concept of device template. For example:

set storage group root.beijing
create device template temp1(
  (s1 INT32 with encoding=Gorilla, compression=SNAPPY),
  (s2 FLOAT with encoding=RLE, compression=SNAPPY)
 )
set device template temp1 to root.beijing

So that root.beijing has the template temp1.
