This add support for rgw loadbalancer based on HAProxy and Keepalived.
We define a single role ceph-rgw-loadbalancer and include HAProxy and
Keepalived configurations all in this.
A single haproxy backend is used to balance all RGW instances and
a single frontend is exported via a single port, default 80.
Keepalived is used to maintain the high availability of all haproxy
instances. You are free to use any number of VIPs. A single VIP is
shared across all keepalived instances and there will be one
master for one VIP, selected sequentially, and others serve as
backups.
This assumes that each keepalived instance is on the same node as
one haproxy instance and we use a simple check script to detect
the state of each haproxy instance and trigger the VIP failover
upon its failure.

The Ubuntu Cloud Archive-related (UCA) defaults in
roles/ceph-defaults/defaults/main.yml were commented out, which means
if you set `ceph_repository` to "uca", you get undefined variable
errors, e.g.
```
The task includes an option with an undefined variable. The error was: 'ceph_stable_repo_uca' is undefined
The error appears to have been in '/nfs/users/nfs_m/mv3/software/ceph-ansible/roles/ceph-common/tasks/installs/debian_uca_repository.yml': line 6, column 3, but may
be elsewhere in the file depending on the exact syntax problem.
The offending line appears to be:
- name: add ubuntu cloud archive repository
^ here
```
Unfortunately, uncommenting these results in some other breakage,
because further roles were written that use the fact of
`ceph_stable_release_uca` being defined as a proxy for "we're using
UCA", so try and install packages from the bionic-updates/queens
release, for example, which doesn't work. So there are a few `apt` tasks
that need modifying to not use `ceph_stable_release_uca` unless
`ceph_origin` is `repository` and `ceph_repository` is `uca`.

Currently the default crush rule value is added to the ceph config
on the mon nodes as an extra configuration applied after the template
generation via the ansible ini module.
This implies two behaviors:
1/ On each ceph-ansible run, the ceph.conf will be regenerated via
ceph-config+template and then ceph-mon+ini_file. This leads to a
non necessary daemons restart.
2/ When other ceph daemons are collocated on the monitor nodes
(like mgr or rgw), the default crush rule value will be erased by
the ceph.conf template (mon -> mgr -> rgw).
This patch adds the osd_pool_default_crush_rule config to the ceph
template and only for the monitor nodes (like crush_rules.yml).
The default crush rule id is read (if exist) from the current ceph
configuration.
The default configuration is -1 (ceph default).

Indeed, `radosgw_interface` is the network interface on rgw only. It is

After restarting each OSD, restart_osd_daemon.sh checks that the
cluster is in a good state before moving on to the next one. One of
the checks it does is that the number of pgs in the state
"active+clean" is equal to the total number of pgs in the cluster.
On large clusters (e.g. we have 173,696 pgs), it is likely that at
least one pg will be scrubbing and/or deep-scrubbing at any one
time. These pgs are in state "active+clean+scrubbing" or
"active+clean+scrubbing+deep", so the script was erroneously not
including them in the "good" count. Similar concerns apply to
"active+clean+snaptrim" and "active+clean+snaptrim_wait".
Fix this by considering as good any pg whose state contains
active+clean. Do this as an integer comparison to num_pgs in pgmap.

BlueStore's cache is sized conservatively by default, so that it does
not overwhelm under-provisioned servers. The default is 1G for HDD, and
3G for SSD.
To replace the page cache, as much memory as possible should be given to
BlueStore. This is required for good performance. Since ceph-ansible
knows how much memory a host has, it can set
`bluestore cache size = max(total host memory / num OSDs on this host * safety
factor, 1G)`
Due to fragmentation and other memory use not included in bluestore's
