config: use level to properly deal with value priority
A higher priority alias will now take precedence over lower priority ones.
This was a requirements step before using alias more widely, especially to
rename existing and established config option.

{"defaultvalue": ""} for -T'json(defaultvalue)' looks weird, but that's
how the templater works. Unknown keywords are evaluated to "".

Simple order checking
---------------------
If file B is read after file A, value from B overwrite value from A.
$ HGRCPATH="file-A.rc:file-B.rc" hg config config-test.basic
value-B
Ordering from include
---------------------
value from an include overwrite value defined before the include, but not the one defined after the include
$ HGRCPATH="file-A.rc" hg config config-test.pre-include
value-included
$ HGRCPATH="file-A.rc" hg config config-test.post-include
value-A
command line override
---------------------
$ HGRCPATH="file-A.rc:file-B.rc" hg config config-test.basic --config config-test.basic=value-CLI
value-CLI
Alias ordering
--------------
The official config is now `command-templates.log`, the historical
`ui.logtemplate` is a valid alternative for it.
When both are defined, The config value read the last "win", this should keep
being true if the config have other alias. In other word, the config value read
earlier will be considered "lower level" and the config read later would be
considered "higher level". And higher level values wins.
$ HGRCPATH="file-A.rc" hg log -r .
value-A
$ HGRCPATH="file-B.rc" hg log -r .
value-B
$ HGRCPATH="file-A.rc:file-B.rc" hg log -r .
value-B
Alias and include
-----------------
The pre/post include priority should also apply when tie-breaking alternatives.
See the case above for details about the two config options used.
$ HGRCPATH="file-C.rc" hg log -r .
value-C
$ HGRCPATH="file-D.rc" hg log -r .
value-included
command line override
---------------------
$ HGRCPATH="file-A.rc:file-B.rc" hg log -r . --config ui.logtemplate="value-CLI\n"
value-CLI
