ngsi2cosmos: flexible clasification of data into many HDFS directories

[fgalan]

Use a text file as ngsi2cosmos configuration in the following format:

<id_pattern1>|<id_type1>|<dataset1>
<id_pattern2>|<id_type2>|<dataset2>
<id_pattern3>|<id_type3>|<dataset3>
...

So, each time a new context element is received, ngsi2cosmos check that table (from top to bottom) to find to with HDFS directory send the data.

Eg.:

OUTSMART.NODE.*|Node|/user/opendata/smartcities/santander/llamas
OUTSMART.AMMS.*|AMMS|/user/opendata/smartcities/santander/llamas
OUTSMART.RG.*|Regulator|/user/opendata/smartcities/santander/llamas
urn:smartsantander:testbed:.*|Sensor|/user/opendata/smartcities/santander/smart
<no se aun :)>|<no se aun :)>|/user/opendata/smartcities/santander/magdalena
