Clint 96d8bd4bf7 [WIP] Support custom max Nomad token name length [supersedes https://github.com/hashicorp/vault/pull/4361] (#5117)
* 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
