[kudu-CR] mini cluster: avoid SIGSEGV when master fails to start up

Hello Todd Lipcon,

I'd like you to do a code review.  Please visit

    http://gerrit.cloudera.org:8080/4006

to review the following change.

Change subject: mini_cluster: avoid SIGSEGV when master fails to start up
......................................................................

mini_cluster: avoid SIGSEGV when master fails to start up

My machine's clock became desynchronized causing MiniCluster-based tests to
SIGSEGV. The root cause appears to be in how we manage the mini_masters_
vector. By resizing it right at the beginning, various code paths later on
may iterate on some number of non-existent masters and dereference empty
shared pointers.
