[PATCH iproute2-next 0/2] ip/tunnel: Unify collect metadata handling

[Serhey Popovych <serhe.popovych@gmail.com>]

With this series I want to unify collect metadata
handling in tunnels:

  1) Use "collect_metadata" name for JSON and
     "external" keyword for non-JSON printing.

     Do not *print* any options when tunnel in
     collect metadata mode: gre6 already do
     this, so just apply to others.

  2) Do not *add* any attributes when configuring
     gre tunnel in collect metadata mode.

     Other tunnels (e.g. gre6, iptnl, ip6tnl)
     alredy do that.

This is next step in ipv4 and ipv6 modules
unification to prepare for merge in the future.

Any comments, suggestions and criticism as always
welcome.

Thanks,
Serhii
