auto build and update microprot_db and HH-suite compatible DB

Databases which we build from publicly available and in-house genomic and metagenomic data need to be updatable and we need to generate scripts to automatically generate updates for HH-suite compatible DB.

We need it for the last part of the pipeline `MSA_hhblits` where we search against UniClust30 and (after this issue is resolved) against our `microprot_db`.

Building the seed `microprot_db` is done, now we need to write a script to automatically update current clustering using `mmseqs` and find an effective way to create HH-suite databases from those updated clusterings.

HHsuite (section 4.9): https://github.com/soedinglab/hh-suite/blob/master/hhsuite-userguide.pdf

I've got some preliminary scripts. If interested, please inquire offline.

No repository files or tests are identified. Start at the MSA_hhblits pipeline stage, then review the MMseqs clusterupdate reference, UniClust's run_hhdatabase.sh, and HH-suite guide section 4.9. Done means an automated process updates the current microprot_db clustering and produces an HH-suite-compatible database for pipeline searches.
