Add better support to avro schema textfield in hermes-console

[szczygiel-m]

Recently we have introduced new hermes console written in vue - #1697
Old hermes-console had a functionality to show avro schema in a preety way, it was introduced in this PR - #1434
Also schema editor such as one introduced in this PR would be great - #1407
We would like to add such improvements in the new hermes-console 😄

I can take a look on auto formatting and highlighting feature in schema editor.

Nice to hear that! To precise - we are currently developing new hermes-console at the branch hermes_console_vue, but in a few weeks we would merge it to the master without squash, so that each contributor would be listed 😄
