Adds option `mon_allow_pool_size_one` which will be disabled by default
to ensure pools are not configured without replicas.
If the user still wants to use pool size 1, they will have to change the
value of `mon_allow_pool_size_one` to true and then have to pass flag
`--yes-i-really-mean-it` to cli command:
Example:
`ceph osd pool test set size 1 --yes-i-really-mean-it`

Introduce a config option called 'mon_warn_on_pool_no_redundancy' that is
used to show a health warning if any pool in the ceph cluster is
configured with a size of 1. The user can mute/unmute the warning using
'ceph health mute/unmute POOL_NO_REDUNDANCY'.
Add standalone test to verify warning on setting pool size=1. Set the
associated warning to 'false' in ceph.conf.template under qa/tasks so
that existing tests do not break.
