For instances, especially when using «--no-name-check» (which skips DNSchecks), we should validate the give name, and also normalize it...

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....
Revert "Get rid of utils.CommaJoin"
This reverts commit 6915bc28fe053e92aa16cf2d974d205f1140219c based on thread onganeti-devel.
Conflicts:
lib/cmdlib.py (due to the error code classification, trivial)
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)....
Some improvements to gnt-node repair-storage
Currently the repair storage has two issues:
- down instances are aborting the operation, even though they should be ignored (it's not technically possible to know their disk status unless we would activate their disks)...
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.
Unify the query fields for the storage framework
This patch unifies the query fields in the storage framework for alltypes. Note that the information is still computed on-demand, so if e.g.the used disk space is not requested for the ‘file’ type, it won't be...
Make gnt-node list-storage more standard
This patch adds support for the -o+field,… format that the other listcommands accept and changes the format of the allocatable field fromsimply str(bool) to Y/N.

The patch modifies LUQueryInstanceData to return the uuid too and alsoadds support for it in the gnt-* scripts.
Change indentation style in commands definitions
Currently, the indentation level for a command's definition depends onthe command name length, and this makes the commands dict unpleasant tothe eye. This patch changes it so that a new line begins right after the...
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
Move the “--readd” option to cli.py
Move the “--no-ssh-key-check” option to cli.py
Move the node flags options to cli.py
This also unifies a little the parameters to the respective options.
Move the “--allocatable” option to cli.py
Unify the “--ignore-consistency” option
Unify the “--non-live” option
Unify the “--new-secondary” option
Unify the “--iallocator” option
This patch also changes the gnt-debug's “--algorithm” intoIALLOCATOR_OPT, since it was the only non-standard use of this (due tohistorical reasons). Since it's just a debug option,backwards-compatibility is not critical here....

This patch fixes a few node readd issues.

Some command line scripts fixes

Fix some issues for lockless queries
This patch converts some more jobs with only queries into cheaper luxiqueries (no job created), and fixes some fallout from the locklessqueries changes.
Enable lockless node queries
Similar to the instance list, this patch enables lockless node queris.“gnt-node list” accepts now the “--sync” flag which enables locking, thedefault is lockless.
