vault: allow overriding implicit vault constraint

There's a bug in version parsing that breaks this constraint when using
a prerelease enterprise version of Vault (eg 1.3.0-beta1+ent). While
this does not fix the underlying bug it does provide a workaround for
future issues related to the implicit constraint. Like the implicit
Connect constraint: *all* implicit constraints should be overridable to
allow users to workaround bugs or other factors should the need arise.

remove accidental project leakage in api/ package

vault: check token_explicit_max_ttl as well

Vault 1.2.0 deprecated `explicit_max_ttl` in favor of
`token_explicit_max_ttl`.
