ETX service update

Removed MLE dependency from ETX module API by unique attribute_index.
Attribute index is same what is used for SW MAC and it works like a
pointer to define pointer to storage list.

Defined etx storage structure which include neighbour etx information
and removed same parameters from mle_table_entry_t.

Added ETX storage allocate function for allocate requirement etx info
entries.

Adaptation interface have separate etx update enable function for
6lowpan and thread

Fixed Unit test's.
