[ticket/14944] Add possibility to search for template loop indexes by key
Adds a new function to the template interface, and implements it in the
context class. The function returns the ordinal index for a specified key,
with the same structure that the key for alter_block_array.
Reuses same code. Remove unneeded references, do nothing for int keys.
Check out of bounds or wrong blockname errors. Added tests.
Remove default parameter value.
