PCBDDC: add lumped variant, aka M_1
This variant, also known as M_1 in the literature, skips extension of
balanced interface values to the interior by solving a Dirichlet
problem. It gives up a factor of H/h in condition number relative to
Dirichlet (standard) BDDC, but may be appropriate for small
subdomains, inexact subdomain solvers, and/or as an ingredient in
composite preconditioners.

Merge branch 'pr1819/jkruzik/feature-pcdeflation/master' [PR #1819]
* pr1819/jkruzik/feature-pcdeflation/master:
PCDeflation.
Implements multilevel deflation preconditioner that can shift part of the spectrum to a predefined value.
Given a full rank deflation matrix W, the deflation preconditioner uses projections Q = W*(W'*A*W)^{-1}*W' and P = I - Q*A.
It computes computes initial guess x0 = x_{-1} - Q*r_{-1} which is the solution on the deflation space.
The preconditioner application consists of P*M^{-1} + factor*Q, where M^{-1} is an additional preconditioner.
See the documentation for PCDEFLATION above PCCreate_Deflation for more detailed description.
