open-vault/command/remount.go
Jeff Mitchell 4239f9d243 Add DynamicSystemView. This uses a pointer to a pointer to always have
up-to-date information. This allows remount to be implemented with the
same source and dest, allowing mount options to be changed on the fly.
If/when Vault gains the ability to HUP its configuration, this should
just work for the global values as well.

Need specific unit tests for this functionality.

Usage: vault remount [options] from to
Remount a mounted secret backend to a new path.
This command remounts a secret backend that is already mounted to
a new path. All the secrets from the old path will be revoked, but
the Vault data associated with the backend will be preserved (such
as configuration data).
If the 'from' and 'to' values of the same, performs an in-place
remount. This allows you to change mount options.
Example: vault remount secret/ generic/
General Options:
` + generalOptionsUsage() + `
Mount Options:
-default-lease-ttl=<duration> Default lease time-to-live for this backend.
If not specified, uses the global default, or
the previously set value. Set to '0' to
explicitly set it to use the global default.
-max-lease-ttl=<duration> Max lease time-to-live for this backend.
If not specified, uses the global default, or
the previously set value. Set to '0' to
explicitly set it to use the global default.
