TBR: tools/{namespace,mounttable}: Sundry tweaks
(1) Include blessing patterns of the server when mounting.
This helps provides clients the guarantee that the endpoint
they communicate with is managed by a server authorized to
use the particular object name in the mounttable.
The tools obtain the set of authorized servers (blessing patterns)
by extracting the blessings from the servers they are trying to
mount.
(2) Add --insecure mode to some commands that avoids the above
guarantee.
