This patch removes code which is no longer used due to refactoring:

- http.InitSsl, last usage removed in commit 33231500 (“Convert RPC
  client to PycURL”)
- rapi.baserlib.MakeParamsDict, last usage remove in commit 4e5a68f8
  (“RAPI: rlib1 removal”)
- rapi.baserlib.ExtractField, last usage removed in commit 028c6b76
  (“RAPI:Fix root list and unittest for it.”)
- qa.qa_utils.AssertNotEqual, last real usage removed in commit
  2f4b4f78 (“Simplify QA commands”) (but it was still imported for a
  while, until we extended pylint to run over the QA code as well)
- qlang._IsHostname, added in commit f8638e28 (“Detect globbing
  patterns as query arguments”) but never used
- cmdlib._BuildNetworkHookEnvByObject, last usage removed in commit
  f22433c0 (“Locking related fixes for networks”)
- NLD constants, which are obsolete—the nbma project is no longer
  maintained and it's not working with current ganeti

This has been a long-standing cleanup item, which we've always
refrained from doing due to the high estimated effort needed.

In reality, it turned out that after some infrastructure improvements
(the previous patches), the actual job queue-related changes are quite
small.

We will need to update the NEWS file later, but so far the RAPI
documentation doesn't mention that the job ID is a string (it only
says it is "a number"), so it doesn't look like it needs update.

Currently, all the CLI helpers in qlang.py and cli.py assume that all
namefields are string, which leads to various breakage in case the're
actually not.

To improve the flexibility of the helpers, we add a bit of
infrastructure for accepting so called "numeric" namefields; this is a
bit of a hack, as a proper fix would actually add QFT_* support to the
helpers, and case for example the regex/globbing on QFT_TEXT, etc. But
that's left for (eventual) later improvement.

A while back, we did cleanup the code and ensured (manually) that use
of OpPrereqError includes an errors.ECODE_* field as second
argument. Since we cannot automate the check for this, it turns out
that more and more such usage has crept over the years, including in
the master code (the use on the CLI side is not as important).

Note that this also uncovered a few errors in ovf.py where the errors
messages were wrongly constructed.

Still looking for a way to automate this check…

In version 0.21, pylint unified all the disable-* (and enable-*)
directives to disable (resp. enable). This leads to a lot of
DeprecationWarning being emitted even if one uses the recommended
version of pylint (0.21.1, as stated in devnotes.rst).

This commit changes all the disable-msg directives to disable.

Short: this patch enables the use of “gnt-instance list '*.site'”.

Detailed description: This patch changes the command line interface code
to try to deduce the kind of filter from the arguments to a “list”
command. If it's a list of plain names an old-style name filter is used.
If filtering is forced or the single argument is potentially a filter,
it is parsed as a query filter string. Any name looking like a globbing
pattern (e.g. “*.site” or “web?.example.com”) is treated as such.

The operators “=*” and “!*” do globbing in filters, e.g.:

With this parser, command line utilities will be able to provide filters
through query2 in a simplistic language. Example filters:

  name == "node3.example.com"
  master or (name == "node4.example.com")
  be/memory == 128 and name =~ /^web/i
  "inst1.example.com" in sinst_list
  status != "up"
  not master

Parts of the syntax came from Python, others from Perl. Documentation
will be added in follow-up patches.
