Enable exclusive lock on MS SQL Server database

MSSqlJdbcLock needs to be created to avoid multiple karaf instances attempting to become master using MS SQL Server with JTDS driver.

Karaf config:

karaf.lock=true
karaf.lock.class=org.apache.karaf.main.DefaultJDBCLock
karaf.lock.level=50
karaf.lock.delay=10
karaf.lock.jdbc.url=jdbc:jtds:sqlserver://x.x.x.x:1433;databaseName=evillarr
karaf.lock.jdbc.driver=net.sourceforge.jtds.jdbc.Driver
karaf.lock.jdbc.user=xxx
karaf.lock.jdbc.password=xxxx
karaf.lock.jdbc.table=KARAF_LOCK
karaf.lock.jdbc.clustername=karaf
karaf.lock.jdbc.timeout=30
