* Nomad: updating max token length to 256 * Initial support for supporting custom max token name length for Nomad * simplify/correct tests * document nomad max_token_name_length * removed support for max token length env var. Rename field for clarity * cleanups after removing env var support * move RandomWithPrefix to testhelpers * fix spelling * Remove default 256 value. Use zero as a sentinel value and ignore it * update docs
