Feature: full-text search in model objects

[exaexa]

Moved from here: LCSB-BioCore/COBREXA.jl#652

Target functionality

It is sometimes quite complicated to quickly find a ID (often numeric one) for a reaction in the model without looking at all possible reaction names and annotations.

There should be a search function, intended for interactive use only, that can quickly find the IDs.

Desired output

search_model(m, "glc")

says something like

Yeah your ID is either  M_glc__d_c or M_glc__d_e
