Dan McArdle 7a817f48ba Add 'generate-ech' command to bssl tool
The tool generates three files: an ECHConfig, its corresponding private
key, and the ECHConfig wrapped in an ECHConfigList.

For example, the following invocation generates the files:

    bssl generate-ech \
      -out-ech-config-list ech_config_list.data \
      -out-ech-config ech_config.data \
      -out-private-key ech.key \
      -public-name foo.example \
      -config-id 0

Now, we can pass the ECHConfig and private key into the 'server' and
'client' commands:

    bssl server -accept 4430 \
        -ech-config ech_config.data \
        -ech-key    ech.key

    bssl client -connect localhost:4430 \
        -ech-config-list ech_config_list.data
