Make the pool size of the pithos backends a configurable setting,
namely PITHOS_BACKEND_POOL_SIZE.

This method optionally accepts a user paramter and used to return
the objects shared to the user and having a specific domain.
This commit extends this functionality and returns also the objects
owned by the user and having the specific domain

Improve performance

Refs: #3510

Before it used to query the database
for all the objects having the specific domain
and finally filtered out the objects to which the user had no access.
Now gets first the allowed_paths for the user and then
brings those having the specific domain

avoid redirecting user to signup view. Notify user the login credentials was

Same as commit 0514662, but for servers.

Delete network from DB when job fails but the action of network is
DESTROY. This case appears when someone tries to remove a network that
has been deleted from Ganeti backend, but not yet from DB.

Change server reconciliation, to get the instances from DB after getting
instances from Ganeti, to decrease the possibility for races.

Fix bug in snf-dispatcher causing wrong updates of VMs from ganeti.
Creation if instance diagnostics must run inside a transaction, because
otherwise, the lock of the vm (select_for_update) is released too early.
Specifally, 'if_update_required' takes a lock on the VM and checks if
the timestamp of the message is newer than the one in the VM. If
diagnostic creation ('create_instance_diagnostic' function) does not run
inside a transaction, the lock is released when the diagnostic row is
inserted in the DB. However, after storing the diagnostic, the VM is
saved in order to update the 'updated' timestamp (otherwise,
MODIFIED_SINCE does not work correctly). In the meantime, another
message may update the VM, and this update will be lost. This commit
wrap 'create_instance_diagnostic' inside transaction to fix this issue.

fix pithos:// redirect params extraction

include reference to the update email configuration guide

Include leave requested and suspended members in the list of approved.

Usage computation for empty accounts used to fail with:
TypeError: 'NoneType' object is unsubscriptable

The weblogin used to return the user uuid.
However, this in 0.14 version had been removed since the uuid
can be retrieved using the POST /tokens authentication method.
However, the old pithos clients have no other way
to get the uuid, so we restore it temporarily.

Register usage for astakos.pending_app even if limit is exceeded.

API method decorator should initialize the AstakosClient with the retry
argument set, in order to avoid errors caused by getting an old
connection from pool.
