[patch] Group APT calls for salt formula install

When installing salt-formula-* on cfg01, we used to call APT for
each package. Instead, handle them all at once.

While at it, stop using colored output on terminals that don't
support it (e.g. 'vt220' used by OPNFV Jenkins).

+Subject: [PATCH] salt-master-setup: Group APT install formulas
+
+Instead of calling `apt install` for each salt formula package that
+we miss, construct a list and install them all at once.
+
+While at it, disable colored output on terminals that don't support
+it, like vt220 (used in OPNFV CI).
