Make the default (non-JSON) output more compact. Looking at RSS
context dumps is pretty much impossible without this, because
default print shows the indirection table with line per entry:
'indir': [0,
1,
2,
...
And indirection tables have 100-200 entries each.
The compact output is far more readable:
'indir': [0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15,
16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29,

As pointed out during review of the --list-attrs support the GET
ops very often return the same attrs from do and dump. Make the
output more readable by combining the reply information, from:
Do request attributes:
- ifindex: u32
netdev ifindex
Do reply attributes:
- ifindex: u32
netdev ifindex
[ .. other attrs .. ]
Dump reply attributes:
- ifindex: u32
netdev ifindex
[ .. other attrs .. ]
To, after:
Do request attributes:
- ifindex: u32
netdev ifindex
Do and Dump reply attributes:
- ifindex: u32
netdev ifindex
[ .. other attrs .. ]

Event and notify handling is quite different from do / dump
handling. Forcing it into print_mode_attrs() doesn't really
buy us anything as events and notifications do not have requests.
Call print_attr_list() directly. Apart form subjective code
clarity this also removes the word "reply" from the output:
Before:
Event reply attributes:
Now:
Event attributes:

--list-attrs also provides information about the operation itself.
So --doc seems more appropriate. Add an alias.

We already use textwrap when printing "doc" section about an attribute,
but only to indent the text. Switch to using fill() to split and indent
all the lines. While at it indent the text by 2 more spaces, so that it
doesn't align with the name of the attribute.
Before (I'm drawing a "box" at ~60 cols here, in an attempt for clarity):

| The timeout, in nanoseconds, of how long to suspend irq|
|processing, if event polling finds events |

It's a little hard to make sense of the output of --list-attrs,
it looks like a wall of text. Sprinkle a little bit of formatting -
make op and attr names bold, and Enum: / Flags: keywords italics.

Enhance the --list-attrs option to recursively display nested attributes
instead of just showing "nest" as the type.
Nested attributes now show their attribute set name and expand to
display their contents.

Do request attributes:
- header: nest -> header
- dev-index: u32

Add a --list-attrs option to the YNL CLI that displays information about
netlink operations, including request and reply attributes.
This eliminates the need to manually inspect YAML spec files to
determine the JSON structure required for operations, or understand the
structure of the reply.
Example usage:
# ./cli.py --family netdev --list-attrs dev-get
Operation: dev-get
Get / dump information about a netdev.
Do request attributes:
- ifindex: u32
netdev ifindex
Do reply attributes:
- ifindex: u32
netdev ifindex
- xdp-features: u64 (enum: xdp-act)
Bitmask of enabled xdp-features.
- xdp-zc-max-segs: u32
max fragment count supported by ZC driver
- xdp-rx-metadata-features: u64 (enum: xdp-rx-metadata)
Bitmask of supported XDP receive metadata features. See Documentation/networking/xdp-rx-metadata.rst for more details.
- xsk-features: u64 (enum: xsk-flags)
Bitmask of enabled AF_XDP features.
Dump reply attributes:
- ifindex: u32
netdev ifindex
- xdp-features: u64 (enum: xdp-act)
Bitmask of enabled xdp-features.
- xdp-zc-max-segs: u32
max fragment count supported by ZC driver
- xdp-rx-metadata-features: u64 (enum: xdp-rx-metadata)
Bitmask of supported XDP receive metadata features. See Documentation/networking/xdp-rx-metadata.rst for more details.
- xsk-features: u64 (enum: xsk-flags)

We default to raising an exception when unknown attrs are found
to make sure those are noticed during development.
When YNL CLI is "installed" and used by sysadmins erroring out
is not going to be helpful. It's far more likely the user space
is older than the kernel in that case, than that some attr is
misdefined or missing.

Move python code to a separate directory so it can be

in selftests and docs.
Also rename ynl-gen-[c|rst] to ynl_gen_[c|rst], avoid
