KUDU-2290: Tool to re-create a tablet
This adds a tool `kudu tablet unsafe_replace_tablet` that can be
used to replace a tablet with another having the same partition
information. This tool is useful when a tablet is has permanently
lost all replicas because it can repair the tablet's table.
Before, the table would have to be recreated to recover from a
permanently lost tablet.
The original tablet is moved to a new, specially-named table,
named like
replaced_<table name>_<table id>_<tablet id>
so that bad replicas are "quarantined" so they can be investigated,
and if a replica of the original tablet can be recovered, its data
can be scanned and recovered relatively easily. Note that, if the
tablet recovers quickly enough after being replaced, its possible
for clients with cache entries from before the replace to read
the rows from the replaced tablet, but eventually this will stop.
