Jeff Mitchell 5119b173c4 Rename helper 'duration' to 'parseutil'. (#2449)
Add a ParseBool function that accepts various kinds of ways of
specifying booleans.

Have config use ParseBool for UI and disabling mlock/cache.

Usage: vault token-renew [options] [token] [increment]
Renew an auth token, extending the amount of time it can be used. If a token
is given to the command, '/auth/token/renew' will be called with the given
token; otherwise, '/auth/token/renew-self' will be called with the client
token.
This command is similar to "renew", but "renew" is only for leases; this
command is only for tokens.
An optional increment can be given to request a certain number of seconds to
increment the lease. This request is advisory; Vault may not adhere to it at
all. If a token is being passed in on the command line, the increment can as
well; otherwise it must be passed in via the '-increment' flag.
General Options:
` + meta.GeneralOptionsUsage() + `
Token Renew Options:
-increment=3600 The desired increment. If not supplied, Vault will
use the default TTL. If supplied, it may still be
ignored. This can be submitted as an integer number
of seconds or a string duration (e.g. "72h").
-format=table The format for output. By default it is a whitespace-
delimited table. This can also be json or yaml.
