Make state.show_* concurrent by default

[AstraLuma]

Description of Issue/Question

state.show_* (state.show_highstate, state.show_top, state.show_sls, etc) currently need the state lock used by state.apply and state.highstate.

As these functions should be read-only, they should default to concurrent so that they don't fail if a state is currently running.

Steps to Reproduce Issue

0. Have a working cluster
1. Start a highstate on a minion
2. Run state.show_top on that minion
