375 radiation boost

Related to #375

[hknahal]

Tested in DEV and QA (version 122.*)

Test case that should pass validation:

Example 1: The reference_radiation_treatment_id field is submitted when a radiation boost was given (radiation_boost = Yes). This should pass validation.
Test files:
sample_registration.txt
donor.txt
primary_diagnosis.txt
treatment.txt
chemotherapy.txt
radiation.txt

Test cases that should fail validation:
Example 1: The reference_radiation_treatment_id is submitted when no radiation boost was given (radiation_boost = No). This should fail validation.
Test files: (same as above except different radiation.txt file)
radiationfail1.txt

Example 2: The reference_radiation_treatment_id is not submitted when radiation boost was given (radiation_boost = Yes). This should fail validation.
Test files (same as above except different radiation.txt file)
radiation_fail2.txt

Pending test case: The submitter_treatment_id submitted in the reference_radiation_treatment_id field does not exist in previous Radiation submissions or the current Radiation submission. This will be tested when ticket icgc-argo/argo-clinical#856 is ready.
