This patch adds a new Lua method index.compact(). If called on
a vinyl index, this method triggers major compaction. For other
kinds of indexes, it is a no-op.

This patch adds index.compact() Lua method. The new method is backed by
index_vtab::compact. Currently, it's a no-op for all kinds of indexes.
It will be used by Vinyl engine in order to trigger major compaction.
Part of #3139

Force major compaction of all ranges when index.compact() is called.
Note, the function only triggers compaction, it doesn't wait until
compaction is complete.
Closes #3139
