Config option 'repo' and 'repo_from' are used in several phases, merge

existing config files that have the old options of 'repo_from' and
'source_repo_from' (which is an alias of 'repo_from').
And 'repo' schema is updated to support repo dict as the value or an

'baseurl' is required in the dict, like:
{"baseurl": "http://example.com/url/to/repo"}

Update pungi-make-ostree to supourt sub-command 'tree', which is just
as the original feature of pungi-make-ostree to compose OSTree tree.
With the change we can add other sub commands later to build other
OSTree artifacts, like the installer image.
Inaddtional to the change, now the the 'tree' command can accept an
optional '--extra-config' parameter to update the original tree
configuration with extra configurations specified in a json file
before composing the OSTree tree.
Example:
pungi-make-ostree tree --repo=/ostree --treefile=/path/to/treefile \
--log-dir=/path/to/log --extra-config=/path/to/extra-config.json
The extra-config file can contains the same configuration as OSTree
phase, the difference is it doesn't understand variant UID as source
repo since it's not ran in the chain of phases. A valid configuration
can be like:
{
"source_repo_from": "http://example.com/repo/x86_64/Server",
"extra_source_repos": [
{
"name": "optional",
"baseurl": "http://example.com/repo/x86_64/optional",
"exclude": "systemd-container",
"gpgcheck": False
},
{
"name": "extra",
"baseurl": "http://example.com/repo/x86_64/extra",
}
],
"keep_original_sources": True
}

instead of that, it writes the extra configurations to a json file,
then 'pungi-make-ostree tree' will take it by option '--extra-config'.

Introduces a new metadata file to track arbitrary files added during the
extra-files phase. This file is placed in the root of each tree and is
called ``extra_files.json``. It is a JSON file containing a single
object, which contains a "header" key with an object describing the
metadata, and a "data" key, which is an array of objects, where each
object represents a file. Each object contains the "file", "checksums",
and "size" keys. "file" is the relative path from the tree root to the
extra file. "checksums" is an object containing one or more checksums,
where the key is the digest type and the value of that key is the hex
digest. Finally, the size is the size of the file in bytes.

"data": [

"file": "GPL",
"checksums": {

The schema is written in Python to reduce duplication. When
configuration is loaded, the validation checks if it's correct and fills
in default values.
There is a custom extension to the schema to report deprecated options.
The config dependencies are implemented as a separate pass. While it's
technically possible to express the dependencies in the schema itself,
the error messages are not very helpful and it makes the schema much
harder to read.
Phases no longer define `config_options`. New options should be added to
the schema. Since the default values are populated automatically during
validation, there is no need to duplicate them into the code.
The `pungi-config-validate` script is updated to use the schema and
report errors even for deeply nested fields.
The dependencies are updated: pungi now depends on `python-jsonschema`
(which is already available in Fedora).

support, the option should contain list of non-blocking architectures.
