Deprecated and removed functionality

Functionality deprecation and remove policy
At Cygnus NGSI agent (cygnus-ngsi), functionality lifecycle is:
- New feature is designed.
- New feature is implemented and released.
- Existent feature is fixed, when required.
- Existent feature is deprecated if a new feature encloses it or becomes unnecesary.
- Existent feature is definitely removed after certain period of time.
While a feature is deprecated, it is still available at cygnus-ngsi, i.e. it can be used and it is documented. Nevertheless, it is no longer supported nor fixed nor improved. A disclaimer is added in the documentation, and optionally, in the logs.
Deprecated features are removed not before 3 developement sprints (usually, a development sprint comprises one month).
This policy will be effective from release 1.6.0 (included). Before that, this policy has been implemented de facto with more or less success.
