syncbased: sb-allocator doesn't create default syncbase db

[azinman]

Currently sb-allocator.v.io doesn't create the default DB necessary for cloud to work. The following steps must occur:

Install the principal & sb binaries

jiri go install v.io/...

Create your principal

$JIRI_ROOT/release/go/bin/principal create $JIRI_ROOT/.v23creds

Bless it via OAuth. On the Vanadium blessings page, just click bless.

$JIRI_ROOT/release/go/bin/principal -v23.credentials=$JIRI_ROOT/.v23creds seekblessings

Create the shared database using the app client id blessing. Notice the , in the id... it's blessing,db

$JIRI_ROOT/release/go/bin/sb --v23.credentials=$JIRI_ROOT/.v23creds -service=/ns.dev.v.io:8101/sb/syncbased-<SYNCBASEID> -create-if-absent=true --db dev.v.io:o:<GOOGLE SIGNIN CLIENTID>,db

At this point you can go to sb-allocator.v.io, click debug on your instance, click Syncbase in the upper right, then verify the database was created. You can't currently view the collections or syncgroups as the website is not authenticated to show them.

All of this is complicated and should be integrated directly into sb-allocator, including authing it to show the collections/syncgroups in debug.

Thanks for the summary, @azinman
A lot has to happen to set this up on your own, including downloading Vanadium. We want the site to do all of this for developers.
