Add remaining data store options

[kfox1111]

We dont support all the spire server datastore sql plugin options. Add the missing ones.

Before the change, we only support:

    ## @param dataStore.sql.databaseType Other supported databases are "postgres" and "mysql"
    databaseType: sqlite3
    ## @param dataStore.sql.databaseName Only used by "postgres" or "mysql"
    databaseName: spire
    ## @param dataStore.sql.host Only used by "postgres" or "mysql"
    host: ""
    ## @param dataStore.sql.port If 0 (default), it will auto set to 5432 for postgres and 3306 for mysql. Only used by those databases.
    port: 0
    ## @param dataStore.sql.username Only used by "postgres" or "mysql"
    username: spire
    ## @param dataStore.sql.password Only used by "postgres" or "mysql"
    password: ""
    ## @param dataStore.sql.options [array] Only used by "postgres" or "mysql"
    options: []

    ## @param dataStore.sql.plugin_data [object] Settings from https://github.com/spiffe/spire/blob/main/doc/plugin_server_datastore_sql.md go in this section
    plugin_data: {}

    ## When an external source creates the secret. The secret should reside in the same namespace as the spire server
    externalSecret:
      ## @param dataStore.sql.externalSecret.enabled Enable external secret for datastore creds
      enabled: false
      ## @param dataStore.sql.externalSecret.name The name of the secret object
      name: ""
      ## @param dataStore.sql.externalSecret.key The key of the secret object whose value is the dataStore.sql password
      key: ""

Moving to separate issue:

Ideally some document or unit test that ensures the sql plugin is configured to match the examples under https://github.com/spiffe/spire/blob/v1.10.0/doc/plugin_server_datastore_sql.md would be included, to ensure that we have the settings documented to correctly derive the examples.

@edwbuck Changes look good to me. Can you give final approval?
