Ability to have a -SNAPSHOT suffix

[ckipp01]

Yet another request 😆 . I'd like the ability to be able to have -SNAPSHOT appended to my snapshot versions. The reason for this is that if you're publishing to sonatype snapshots they require your version to actually end in -SNAPSHOT. You can also see this in sbt-dynver, which is what I'm using to using. In their readme you can see:

If you're publishing to Sonatype sonashots then enable ThisBuild / dynverSonatypeSnapshots := true to append "-SNAPSHOT" to the version if isSnapshot is true (which it is unless building on a tag with no local changes). This opt-in exists because the Sonatype's snapshots repository requires all versions to end with -SNAPSHOT.

Do you think this could be added? Maybe inside of format we can add a appendSnapshot: Boolean = false so that users could just turn this on, and if it's detected that it's a "snapshot" then everything else stays the same but -SNAPSHOT gets added at the end. wdyt?

TBH, I though we already support -SNAPSHOT formatting, but I again tested it and found there is a small piece missing, as the commitCount can't be disabled completely.

So, the following format-call does almost properly render a SNAPSHOT version, except we still print the commit count.

.format(
  countSep = "-SNAPSHOT", 
  dirtyHashDigits = 0, 
  dirtySep = "", 
  revHashDigits = 0, 
  revSep = ""
)
// => "5.3.7-SNAPSHOT30

I tend to re-use the commitCountPad settings with a negative value to signal, that we don't want a commit count at all. WDYT?

-* `commitCountPad: Byte = 0` - if greater than zero, the commit count will be padded to the given length
+* `commitCountPad: Byte = 0` - if greater than zero, the commit count will be padded to the given length. If negative, no commit count will be printed 

.format(
  commitCountPad = -1, 
  countSep = "-SNAPSHOT", 
  dirtyHashDigits = 0, 
  dirtySep = "", 
  revHashDigits = 0, 
  revSep = ""
) 
// => 5.3.7-SNAPSHOT

We could add a def formatMavenSnapshot with this setup.
