Joshua Boniface 01959cb9e3 Implementation of RBD volumes and snapshots 
Adds the ability to manage RBD volumes (add/remove) and RBD
snapshots (add/remove). (Working) list functions to come.

Joshua Boniface b50b2a827b Add forced delays after pool add/remove 
Prevents returning immediately to give the cluster some breathing
room before the admin can do other commands. Keep the write lock
as well to prevent other clients from attempting this as well.

Joshua Boniface 3ba3c339a7 Show vCPU count on CLI output 
Showing the static, total number of CPUs was pointless. Instead,
show the number of allocated vCPUs. To preserve space, no longer
show the host CPU count in the list.

Joshua Boniface 62a71af46e Implement locking for unflush as well 
References #32
 2019-05-11 00:13:03 -04:00
Joshua Boniface c19902d952 Implement flush locking for nodes 
Implements a locking mechanism to prevent clobbering of node
flushes. When a flush begins, a global cluster lock is placed
which is freed once the flush completes. While the lock is in place,
other flush events queue waiting for the lock to free before
proceeding.

Modifies the CLI output flow when the `--wait` option is specified.
First, if a lock exists when running the command, the message is
tweaked to indicate this, and the client will wait first for the
lock to free, and then for the flush as normal. Second, the wait
depends on the active lock rather than the domain_status for
consistency purposes.

Closes #32

Joshua Boniface 045ad131af Update node.py to allow API use 
Addresses #33

Joshua Boniface b6ecd36588 Implement domain log watching 
Implements the ability for a client to watch almost-live domain
console logs from the hypervisors. It does this using a deque-based
"tail -f" mechanism (with a configurable buffer per-VM) that watches
the domain console logfile in the (configurable) directory every
half-second. It then stores the current buffer in Zookeeper when
changed, where a client can then request it, either as a static piece
of text in the `less` pager, or via a similar "tail -f" functionality
implemented using fixed line splitting and comparison to provide a
generally-seamless output.

Enabling this feature requires each guest VM to implement a Libvirt
serial log and write its (text) console to it, for example using the
default logging directory:

```
<serial type='pty'>
    <log file='/var/log/libvirt/vmname.log' append='off'/>
<serial>
```

The append mode can be either on or off; on grows files unbounded,
off causes the log (and hence the PVC log data) to be truncated on
initial VM startup from offline. The administrator must choose how
they best want to handle this until Libvirt implements their own
clog-type logging format.

Joshua Boniface 1126382ac9 Initial API including fixes to common functons 
Some functions were doing `click.echo` inside themselves; don't
do that as it's not API compatible, just return everything.

Joshua Boniface f198f62563 Massive rejigger into single daemon 
Completely restructure the daemon code to move the 4 discrete daemons
into a single daemon that can be run on every hypervisor. Introduce the
idea of a static list of "coordinator" nodes which are configured at
install time to run Zookeeper and FRR in router mode, and which are
allowed to take on client network management duties (gateway, DHCP, DNS,
etc.) while also allowing them to run VMs (i.e. no dedicated "router"
nodes required).
