Add more functional tests + change describes numbers associated

[mapedraza]

Added the following new tests:

   0540 - Group with explicit attrs: JEXL expression based on measure resulting boolean + active attributes + static attributes
      ✔ A - WHEN sending both provisioned and not object_ids (measures) through http and being the explicitAttrs JEXL result true IT should store only explicit attrs into Context Broker
      ✔ A - WHEN sending both provisioned and not object_ids (measures) through http and being the explicitAttrs JEXL result false IT should store all attrs into Context Broker
    0550 - Group with explicit attrs: JEXL expression based on measure resulting an array + active attributes + static attributes
      ✔ A - WHEN sending (a&&b) IT should store only [attr_a,attr_b] attrs into Context Broker
      ✔ B - WHEN sending only a IT should store only [attr_a,static_b] attrs into Context Broker
      ✔ C - WHEN sending only b IT should store only [{object_id:b}] attrs into Context Broker
      ✔ D - WHEN no sending any defined case IT should store [static_a,static_b] attrs into Context Broker
    0600 - Group multientity attrs
      ✔ A - WHEN sending provisioned object_ids (measures) through http IT should store both entities into Context Broker
    0610 - Group multientity attrs + value JEXL expression
      ✔ A - WHEN sending provisioned object_ids (measures) through http IT should store both entities into Context Broker
    0620 - Group multientity attrs + multientity ID JEXL expression
      ✔ A - WHEN sending provisioned object_ids (measures) through http IT should store both entities into Context Broker
    0700 - Group JEXL entityNameExpression
      ✔ A - WHEN sending provisioned object_ids (measures) through http IT should store the entity with the expression generated ID into the Context Broker
    0700 - skipValue test
      ✔ A - WHEN not matching skip conditions IT should store the entity with all the values (attr_a, attr_b, static_a) into the Context Broker
      ✔ B - WHEN matching skip conditions for attr_b IT should store the entity with some of the values (attr_a, static_a) into the Context Broker
      ✔ C - WHEN matching skip conditions for attr_a and attr_b (expression result) IT should store the entity with only some of the values (static_a) into the Context Broker

Placeholder for multigroups tests. Not working in lib, probably it should work at agent level. NTC
