erp5: Update output schema.

hosts-dict values cannot be domain names.
memcached entries are implementation-independent (no mention of kumofs
anymore).
relational database information (which does not follow above memcached
rule, sadly, naming mariadb explicitly) is published in two lists.
Add minimal patterns to document what requester should expect.
Document deadlock-debugger-password".
Drop non-standard "optional" property from jupyter-url declaration.
