Add environment variable to override admin password

[leroyguillaume]

Add new environment variable NEXUS_ADMIN_INIT_PASSWORD to override admin password at the first Nexus start.

If this variable is set, the Nexus start a first time to initialize its files. Once started, it is stopped and the security Orient database is updated. The hash of the password is generated by Apache Shiro CLI. Then, Nexus is restarted.

@leroyguillaume please rebase this.

In my use case we pre-generate passwords to ensure it meets our security requirements. So we would love to have an easy way to idempotently set the password.

What do we need to do to get this merged @jdillon @ajbrown @mpuglin ?
