Juniper/contrail reset_db*.sh scripts can hang

[Krzysztof Klimonda]

tools/reset_db.sh and tools/reset_db_psql.sh have a potential for hanging on the command that redirects stdin into `docker exec` call.

When that happens, quick look through the affected VM shows that `docker exec` is waiting for the spawned process to finish, and mysql/psql calls wait on readv(0, indefinitely (fd 0 is stdin). This could be docker version specific, or could be caused by piping large .sql files.

Lower job timeout to 90 minutes

We're hitting some random deadlocks on redirecting stdin to docker exec
calls. This review lowers a timeout for the job to 90 minutes, so that
reviews stuck on that fail faster.

Mount sourcedir in DB containers

Passing huge init SQL files via stdin to docker exec caused random
deadlocks. To avoid this files are mounted and read by DB clients inside
containers.

Note that containers in dev environments should be rebuilt
with `make testenv`.
