Can't handle ssh key bigger than 4096 lengh

Because of guacamole_connection_parameter/parameter_value site set to 4096, keys bigger than 1024 bits can't be used.
Update to 8192 could be enough (keys bigger than 10240 bits).

Needs :
. Database creation : change parameter_value from 4096 to 8192 (incubator-guacamole-client/extensions/guacamole-auth-jdbc/modules/guacamole-auth-jdbc-mysql/schema/001-create-schema.sql) + (incubator-guacamole-client/extensions/guacamole-auth-jdbc/modules/guacamole-auth-jdbc-postgresql/schema/001-create-schema.sql)
. Mysql Database upgrade : ALTER TABLE guacamole_connection_parameter MODIFY parameter_value VARCHAR(8192);
. don't know for postgresql
