Allow cluster copy file over the replication net
This patch introduces the option “--use-replication-network” for thecluster copyfile functionality, which is useful if the primary andsecondary network are significantly different (see issue 32).

Rename SSL_CERT_FILE to NODED_CERT_FILE
To be consistent with RAPI_CERT_FILE, the rather generic named“SSL_CERT_FILE” constant is renamed to “NODED_CERT_FILE”. The actual filename is not changed.
Rightname confd's HMAC key
Currently, the ganeti-confd's HMAC key is called “cluster HMAC key” orsimply “HMAC key” everywhere. With the implementation of inter-clusterinstance moves, another HMAC key will be introduced for signing criticaldata. They can not be the same, so this patch clarifies the purpose of the...

Further pylint disables, mostly for Unused args
Many of our functions have to follow a given API, and thus we have tokeep a given signature, but pylint doesn't understand this. Therefore,we silence this warning.
The patch does a few other cleanups.
Remove more unused variables
This removes unused variables in the rest of the code (outside lib/).

Add targeted pylint disables
This patch should have only:
- pylint disables- docstring changes- whitespace changes
Remove quotes from CommaJoin and convert to it
This patch removes the quotes from CommaJoin and converts most of thecallers (that I could find) to it. Since CommaJoin does str(i) for i inparam, we can remove these, thus simplifying slightly a few calls....
Introduce a wrapper for hostname resolving
Currently a few of the LU's CheckPrereq use utils.HostInfo which raisesa resolver error in case of failure. This is an exception from thestandard that CheckPrereq should raise an OpPrereqError if the error isin the 'pre' phase (so that it can be retried)....
Convert the rest of the OpPrereqError users
This finishes the conversion of OpPrereqError creation to two-argumentstyle. Any leftovers as one-argument are not breaking anything, justlosing information about the errors.
Adding '--no-ssh-init' option to 'gnt-cluster init'.

Remove explicit DEBUG_OPT and add it by default
Since >90% of the commands take the “--debug” option, and all shouldactually take it (the gnt-job command is currently missing it), it makessense to simply remove this and add it by default in cli.py.
Unify the “--secondary-ip” option
Unify the “--no-lvm-storage” option
Unify the “--enabled-hypervisors” option
This also required a change, as one of the cases used a differentdefault.
Unify the “--nic-parameters” option
Unify the “--candidate-pool-size” option
This required a slight tweak since in init we want a different default.
Unify the “--vg-name” option
Move the “--yes-do-it” option to cli.py
Move the “--no-voting” option to cli.py
Move the “--mac-prefix” option to cli.py
The default has also been changed to None as this will be useful oncecluster modify will be able to change this setting too.
Unify the last “--hypervisor” (as list) option
This third form takes a list of name+options, and is used only ingnt-cluster. Who knew that we have three forms of ‘-H’?
Unify the “--node” (as list of nodes) option
Unify the “--backend-parameters” option
This is not straight-forward. First, gnt-cluster had“--backend-parameters” wheres the rest of the script had just“--backend”. I settled on the full form, since one can always abbreviateoptions, but not vice-versa....
Add an error-simulation mode to cluster verify
One of the issues we have in ganeti is that it's very hard to test theerror-handling paths; QA and burnin only test the OK code-path, sinceit's hard to simulate errors.
