Undo reversion of PR 1250

[robinbb]

@Isaac-DeFrain the PR produces new faulty behaviour with 'db-version', which is supposed to tell the database version, but now gives:

Unable to connect to the Unix domain socket server: No such file or directory (os error 2)

It is important that no server exist when that command is run.

Note that in your original PR, the following command line options should not have appeared in 'database' commands, since they are offline commands:

      --web-hostname <WEB_HOSTNAME>
          Web server hostname for REST and GraphQL [default: localhost]
      --web-port <WEB_PORT>
          Web server port for REST and GraphQL [default: 8080]

Create a new mina indexer database to use with `mina-indexer start`

Usage: mina-indexer database create [OPTIONS] [GENESIS_CONSTANTS] [CONSTRAINT_SYSTEM_DIGESTS]... [-- <PID>]

Arguments:
  [GENESIS_CONSTANTS]             Path to the genesis constants (JSON)
  [CONSTRAINT_SYSTEM_DIGESTS]...  Override the constraint system digests
  [PID]                           Indexer process ID

It is impossible to dictate a process ID, so that should not be taken as an argument.

 def db_dir(block_height)
   BASE_DIR + '/db/' + DB_VERSION + '-' + block_height.to_s

So, also just making 'mina-indexer db-version' should work, too.

I could also push the above hack on top of the reversion to this reversion while 'mina-indexer db-version' gets fixed?
