In this patch, we make use of the CBOR (RFC8949) encode helper functions
from the previous commit to implement '+cbor' encoding option for log-
formats. The logic behind it is pretty similar to '+json' encoding option,
except that the produced output is a CBOR payload written in HEX format so
that it remains compatible to use this with regular syslog endpoints.
Example:
log-format "%{+cbor}o %[int(4)] test %(named_field)[str(ok)]"
Will produce:
BF6B6E616D65645F6669656C64626F6BFF
Detailed view (from cbor.me):
BF # map(*)
6B # text(11)
6E616D65645F6669656C64 # "named_field"
62 # text(2)
6F6B # "ok"
FF # primitive(*)
If the option isn't set globally, but on a specific node instead, then
only the value will be encoded according to CBOR specification.
Example:
log-format "test cbor bool: %{+cbor}[bool(true)]"
Will produce:
test cbor bool: F5
