Feature request: Allow Parameter Names to be longer than 64 characters

[jusiskin]

Describe the problem

Originally reported in aws-deadline/deadline-cloud#664

Job parameter names have a maximum length of 64 characters. This is restrictive since:

Proposed Solution

Extend the limit to 128 or 256 characters.

<PROJECT>_<SCENE>_<SHOT>_<REVISION>_<DESCRIPTION>
