Joshua Boniface a48bf2d71e More gracefully handle none selectors
Allow selection of "none" as the node selector, and handle this by
always using the cluster default instead of writing it in.

Joshua Boniface 8f705c9cc2 Add cluster backup + restore functionality
Adds cluster backup (JSON dump) and restore functions for use in
disaster recovery.

Further, adds additional confirmation to the initialization (as well as
restore) endpoints to avoid accidental triggering, and also groups the
init, backup, and restore commands in the CLI into a new "task"
subsection.

Joshua Boniface d74cf00feb Lint: F821 undefined name 'data'
Not really a lint, but simply makes the image uploader work the same way
that the OVA uploader does. May need more tweaking if this broke it.

Joshua Boniface 6c56d45345 Lint: F821 undefined name 'config'
This variable is set after importing these files by the flaskapi module.
Thus, simply set a default at the top of each file to avoid linting
errors.

Joshua Boniface ec0b8acf90 Support per-VM migration type selectors
Allow a VM to specify its migration type as a default choice. The valid
options are "default" (i.e. behave as now), "live" which forces a live
migration only, and "shutdown" which forces a shutdown migration only.
The new option is treated as a VM meta option and is set to default if
not found.

Joshua Boniface ffaa4c033f Improve handling of large file uploads
By default, Werkzeug would require the entire file (be it an OVA or
image file) to be uploaded and saved to a temporary, fake file under
`/tmp`, before any further processing could occur. This blocked most of
the execution of these functions until the upload was completed.

This entirely defeated the purpose of what I was trying to do, which was
to save the uploads directly to the temporary blockdev in each case,
thus avoiding any sort of memory or (host) disk usage.

The solution is two-fold:

  1. First, ensure that the `location='args'` value is set in
  RequestParser; without this, the `files` portion would be parsed
  during the argument parsing, which was the original source of this
  blocking behaviour.

  2. Instead of the convoluted request handling that was being done
  originally here, instead entirely defer the parsing of the `files`
  arguments until the point in the code where they are ready to be
  saved. Then, using an override stream_factory that simply opens the
  temporary blockdev, the upload can commence while being written
  directly out to it, rather than using `/tmp` space.

This does alter the error handling slightly; it is impossible to check
if the argument was passed until this point in the code, so it may take
longer to fail if the API consumer does not specify a file as they
should. This is a minor trade-off and I would expect my API consumers to
be sane here.

Joshua Boniface ce60836c34 Allow enforcement of live migration
Provides a CLI and API argument to force live migration, which triggers
a new VM state "migrate-live". The node daemon VMInstance during migrate
will read this flag from the state and, if enforced, will not trigger a
shutdown migration.

Joshua Boniface 56a9e48163 Normalize all return messages
Ensure all API return messages are formated the same: no "error", a
final period except when displaying Exception text, and a regular spaced
out format.

Joshua Boniface 8678dedfea Revert "Implement wait for node coordinator transition"
This reverts commit 0aefafa7f7.

This does not work since the API goes away during the transition.

Joshua Boniface e419855911 Support converting types during upload
Allow the user to specify other, non-raw files and upload them,
performing a conversion with qemu-img convert and a temporary block
device as a shim (since qemu-img can't use FIFOs).

Also ensures that the target volume exists before proceeding.

Joshua Boniface ce985234c3 Use consistent naming of components
Rename "pvcd" to "pvcnoded", and "pvc-api" to "pvcapid" so names for the
daemons are fully consistent. Update the names of the configuration
