Rework tag translator

[rtroilo]

Rework of OSHDB(jdbc/h2) connection and TagTranslator handling.

Description

• OSHDB(Jdbc/h2) Database now depends on a javax.sql.DataSource instead of a single java.sql.Connection.
• OSHDBH2, creates, if not otherwise provided, a org.h2.jdbcx.JdbcConnectionPool as as DataSource
• OSHDBJdbc, don't create a DataSource by it self, so a DataSource has to be provided. Like HikariCP or others.

⚠️The provided DataSource have to be thread-safe!

• Keytables connections and TagTranslator are now directly provided be the OSHDBDatasource.

Before:

var oshdb = new OSHDBJdbc(conn);
var keytables = new OSHDBJdbc(conn);
var mr = OSMEntitySnapshotView.on(oshdb)
          .keytables(keytables)
          …

after:

var oshdb =  new OSHDBJdbc(dsGrid, dsKeytables);
var tagTranslator = oshdb.getTagTranslator();
var mr = OSMEntitySnapshotView.on(oshdb)
          …

• Renaming TagTranslator OSHDB to OSM methodes to lookupTag and lookupRole
• new functionality added to TagTranslator for bulk loading.

Set<OSHDBTag> tags;
Map<OSHDBTag, OSMTag> mapping = tagTransator.lookupTag(tags);

OSMEntity osm;
Map<OSHDBTag, OSMTag> mapping = tagTransator.lookupTag(osm.getTags());
