ACCUMULO-3135 Modify server-side table-operations to throw ThriftTableOperationException when table doesn't exist

The server-side implementations of the table operations typically
follow the pattern of: accept table name, get table id, check
permission, run table operation.

Fetching the table id does a (trusted) check of whether or not
the table that was requested to operate upon actually exists or
not (we don't want to blindly accept table IDs from users in most
cases). However, there is a race condition in which a table may
be deleted after we fetch the table ID and before we can check the
permissions for the user on said table.

SecurityOperation only throws ThriftSecurityExceptions. While this
makes sense in the context of the SecurityOperation class, we have
to translate a ThriftSecurityException for a nonexistent table
into a ThriftTableOperationException so that the client implementation
will throw a TableNotFoundException instead of an AccumuloSecurityException.
